New GLOCK 46 With Rotating Barrel Lockup for German Police Trials

A German gun magazine called DWJ reports that they had a chance to take a look at a new Glock 46 designed for German police trials. It is a 9x19mm Glock which looks to be a Gen5-based and compact size pistol. It gets even more interesting when you learn that the Glock 46 has a different locking mechanism. It still uses a short recoiling barrel, however, instead of the traditional Browning tilting barrel lockup seen in all Glock pistols, the Glock 46 uses a rotating barrel!

Images from

Another feature is the ability to be disassembled without pulling the trigger. The beavertail looks to be enlarged, too. Also, the slide cover plate protrudes further than normally seen on Glock pistols. It even seems to be attached to the striker assembly.

Apparently, there are two locking lugs on the barrel which lock the barrel to the slide via the corresponding locking recesses cut into the slide. The rear lug on the barrel rides in the helical cut inside the new locking block thus rotating the barrel and locking/unlocking the action.

Below are some images from a Glock patent application (US20170198993A1).

The most of what we can tell right now are just assumptions based on what is shown in the images. I think very soon there will be more details released about the Glock 46.

It would be interesting to know what other differences from the conventional Glock have our readers noticed?

  • Kelly Jackson

    Why tho

    • Mark

      More recoil mitigation in that locking mechanism. Also you don’t have the barrel tilting up creating a vertical impact. Might accommodate more suppressor options.

      • Justin Roney

        Except they would have to use something like the HK three lug system so the suppressors didn’t unscrew while firing.

        • I don’t think silencers are a huge concern for police forces.

          • Justin Roney

            True, but I can’t imagine Glock spent the R+D money on such a significant design change for only one contract. That would be as silly as making a bunch of small design improvements and calling it a whole new generation of pistol. Waaait a sec…

          • The Gen 5 maybe a whole set of small changes, but it is a pretty solid pistol. The trigger is better, and the ejection is more consistent. The only thing I dislike is the cut out on the front of the trigger when combined with the rear cut out (pick one of the other Glock).

          • It’s pretty solid – for Glock. By any other manufacturer or aftermarket standard, the design improvements are sadly lacking.

            The return to no finger grooves is simply reverting to Gen 2 ergonomics. And the new finish is to fix the abysmal finish introduced in post 2010 Glocks. Improved ejection is simply fixing a problem that manifested in the Gen 4…

            So most of the “improvements” are fixing issues Glock introduced with the Gen 3/ Gen 4 models, not actual new design features never before seen in the Glock lineup.

            If Glock actually spent 5 Euros more on the production cost, they could have created a pistol that would have saved hundreds of dollars in upgrades for the consumer – and actually have made a credible claim to perfection:

            -Nickel Teflon coating the trigger group, firing pin block, and striker for smoother trigger pull.
            -MIM metal sights with orange plastic insert for the front sight and U notch rear (as a sort of budget HD sight). Hell, even a plastic version of this would be welcome.
            -Front slide serrations
            -Frame with actually removable backstraps to allow grip angle changes, rather then the ridiculous stack on backstraps that no other company uses.

          • Kelly Jackson

            I thought the 5th gen Glock was called the P10c?

          • Or the new M&P 2.0C, which also closely matches the dimensions of the G19.

          • michael

            -frame with removable backstraps

            This alone is the feature that would have put them back on the list of pistols I would consider owning. The gen 5 has clarified that they don’t intend to ever do that. Glock, like the 1911, is only relevant today due to how prolific they became before obsolescence. Thus lots of aftermarket support. Pretty much any modern striker gun is superior in ergonomics, and most have no downsides compared to a Glock. Walther, HK, CZ, etc. are all superior.

          • Amplified Heat

            Well, the other company well known for riding the coat tails of a single successful design with few improvements also likes to blow lots of R&D money on rather ill-conceived designs like the G11 and G36

        • Something like Griffin Armaments m4sd would work for counter rotation. But it would also mean turning the silencer, causing simmilar issues to the short recoil browning design with heavy weights on the end. Albeit maybe not as pronounced?

        • iksnilol

          Or just make the barrel rotate the opposite way (or go for left handed threads/rifling).

          • ARCNA442

            Doesn’t the barrel rotate both ways regardless since it has to return to battery as well?

          • iksnilol

            I guess, didn’t think of that.

          • ostiariusalpha

            The unlocking of the breach is much more rapid and violent than the return to battery, so that would be the part you would want to concentrate on.

          • iksnilol

            So I was sorta correct after all? Not bad for a monday, keeper of gates, sayer of things that maketh me feel good.

      • John Morrison

        Muzzle tilt helps ammo feeding, so reliability may suffer. Also, no recoil mitigation. Same force with a better position may help muzzle flip and follow up shots. Nothing in this design reduces recoil, unless it weighs significantly more.

  • Ryfyle

    Just a small step till we see some nifty Glock that’s a Gas Operated. The world needs more of those.

    • Anonymoose

      Glock Brand Deagle in .500 Magnum. Fund it!

      • Nashvone

        Somewhere out there is a piece of steel that destined to become a slide stop pin and it’s wishing you would shut the hell up. Personally, I would pull the trigger on it.

      • Ryfyle

        I ded from that.

    • George

      Wait for it…

      …you know what I’m going to do…

      …Direct Impingement!

      • Ryfyle

        Like hardcore French Style or Stoners Space Magic Style?

    • Juice

      It’s still so odd that no company has made a 9×19 competition handgun that’s based off of the Desert Eagle’s action. Deagles are really accurate pistols.

      • Ryfyle

        Well the materials tech is there, in fact, I was thinking something along the lines as using the slide like a piston.

      • I imagine the level of engineering required makes it a very difficult nut to crack. Sig managed it with the MPX’s short-stroke piston, but they’re about the only ones I can think of.

        • demophilus

          The Swedes had a gas operated 9mm prototype in the 60s that allegedly influenced the Wildey design — the Carl Gustafs GF, I think, but it might have been Husqvarna. Didn’t catch on.

          I think the problems are complexity and cost. 9mm bullet weights and pressures vary considerably; you might need a tunable gas system, which would add engineering and expense.

          I’d like to see someone make an inexpensive 9mm target pistol, but reckon it would be cheaper to update the Lahti.

  • Disgruntled

    A Glock with even less recoil? Sign me up.

    • Patrick R. – Senior Writer

      That was my first thought.

    • Choogisaurus Rex

      Imagine a glock 17 with the rotating barrel and a compensator.

      • Patrick R. – Senior Writer

        I was wondering if that would work properly. Time to research!

        • iksnilol

          Get a Rex 1 and slap on a compensator. Both are inexpensive.

          Y’know, for science!

          • Giolli Joker

            I guess you’re confusing the Slovenian Rex 1 (tilting barrel) with the Slovakian Grand Power (rotating barrel).

          • iksnilol

            I was thinking of the Sig “clone” with the rotating barrel.

            Grand Power is also a good choice.

          • Giolli Joker

            Yep, but I don’t know which Sig copy has a rotating barrel.
            Commercially available AREX Rex 1 operates the same way as Sig: tilting barrel.

          • iksnilol

            Oh my god, I’VE BEEN MISTAKEN!

      • Anonymoose
    • John Morrison

      Sorry, no effect on recoil. If it gives lower bore axis, then there is less muzzle flip. Also, the straight back movement of the barrel should be more accurate than the current barrel that cants upward on recoil.

  • nova3930

    I wonder what the requirement was that drove that solution

    • Some Guy

      The requirement fort the state police of Bavaria is just a replacment for their old P7 with a bigger magazine. The Walther PPQ, the HK SFP 9/VP 9 and the Sig P320 are in the running. There are now only three other polices(Berlin, Saxony and the Polizei DBT) with a low capacity gun. None of them are big enough to really be worth this effort(and most likly they only want a higher capacity gun).

      • RSG

        Wait- are you saying the Bavaria State Police use the HK P7 squeeze cocker as their issued pistol? Or is there a different P7 I’m overlooking.

        • Some Guy

          Yes the Bavarian state police is currently using the P7 squeeze cocker. Now that replacment parts are becoming harder to get they want a new gun.

          • Mr._Exterminatus

            Coolest duty gun ever.

      • nova3930

        Right, but there are obviously sub-requirements in that as far as size, caliber, capacity, reliability, etc etc etc. What of those requirements made them switch to something very very different from typical.

        • Some Guy

          The only other requirement are based on reliability, a higher capacity and a the ability to modify the grip of the gun for the Bavarian trial(the whole thing is not really scientific). The Bavarian police let about 10% of active duty officers decide after testing all guns. The other police agencies i mentioned have not even started the replacment process. I have to add that saxony already has their new VP9s. So only Berlin is left with about 10000 guns for a contract

      • HKfan

        Don’t be surprised if they just go with the VP9. German police depts. are already placing VP9 orders and before that they preferred the P30 and P99. Yo do see Glock here and there, which is a fine option, but they tend to go with HK first, Walther or Sig second, and Glock third.

  • Anon

    “The beavertail looks to be enlarged”
    I think this is a pretty sure thing, but I applaud your deference to caution

  • Aono

    In theory the two lug lockup should result in more consistency and better accuracy. I am mostly curious how someone is going to solve the rotating barrel/attached suppressor conundrum. Ideally someone would create an industry standard around a hush puppy style attachment and glock, beretta, grand power et al would hop aboard… this is the only disadvantage I see vis a vis browning lockup and even then they had to invent a Nielsen device to get that to work.

    • Amplified Heat

      They already solved it; look up the Steyr TMP

  • Jon Fox

    This would make me buy a Glock.

    • Stuki Moi

      ??? Because the barrel rotates?

      • iksnilol


        • Stuki Moi

          To each their own, I guess….

          Man, I always really wanted a Glock, but that darned barrel man,.. It just doesn’t rotate…….

      • Jon Fox

        Cause it not the same thing as the last 5 generations that other companies have done better.

  • Justin Roney

    Wait, I thought Glocks were perfect!!! What gives???

    (Waits patiently to be accused of heresy.)

    • helitack32f1

      Oooooh, definitely SO clever. I hadn’t heard that one before! So original too.

      • Justin Roney

        Well SOMEBODY had to say it. 😁

        (Yes, in the interest of full disclosure, I also own a Glock.)

  • Grant

    It didn’t exactly set the world on fire when Beretta tried it with their Cougar series.

    I’m always willing to try something new, but I too am curious what this brings to the table compared to the traditional Browning designs that currently rule the world of handguns.

    • Hrachya H

      I guess that must’ve been a German police requirement.

      • They might have wanted a spaghetti gun, so they wrote that rotating lock up in the spec.

      • 2wheels

        That’d be a strange requirement to have.

    • Polaritypictures Ken

      Colt tried it was well and it failed.

      • Grant

        Pretty much everything about the Colt 2000 was a fail. At least the Beretta worked. From what I remember it got good reviews. They even made a .45. It was just never really popular.

        The Beretta design is still available from Stoeger, but I’m not sure who actually makes it now. I’m guessing if it was a total POS it would have been dropped all together.

        • mig1nc

          Made in Turkey I believe, using the original Beretta machinery.

        • 2wheels

          Cougars are solid guns, I’m not sure why they never took off as Beretta made guns. The Turkish made Stoegers are a great value though. I liked mine except for the slide mounted safety/decocker, which is ultimately what made me decide to gift mine to a friend.

        • Andrew

          The Beretta design is still available from Beretta. It’s now called the PX4 instead of Cougar, and is available in several models. It is also quite customizable as far as trigger and safety options, like an HK, and now has a plastic frame with interchangeable backstraps.

        • Yeah, the Colt 2000 was a massive ball of disappointment, made from suck, fail, and sadness.

      • HKfan

        Colt is Colt. Innovation and making firearms fit for the 21st century is not in their vocabulary

    • Amplified Heat

      The main issue with the Beretta was marketing and ergonomics. Largely due to Glock’s influence, a big chunk of the consumer market thinks anything but a brick with a finger-grooved handle attached to it is ‘ugly’ or ‘girly’ looking (somehow Walther gets a pass). The PX4’s styling was more ornate than much of the competition, even though its grip was probably the most comfortable option for a double stack. Ergonomically, the pistol was rather wide and top heavy, its size making it a direct competitor for the M9/92 service pistol, which was already much more well known and popular. Lastly, Beretta insisted upon its idiotic slide-placed safety design, which in addition to making a rather stiff-springed slide borderline painful to grasp, jutted out on both sides nearly a full quarter inch to make the gun feel even wider.

      • Nashvone

        Walther pistols actually have some curves to them. Think of them more as an artistic sidewalk paver instead of the ordinary brick.

      • Andrew

        Theres a low profile lever available for the px4, and also the “F” model (safety and decocker) can be converted easily to a “G” model (decocker only/no safety). Additionally, one can buy a DAO “D” model or a perpetually half-cocked double action called the “C” for “constant action” for a more striker-like trigger feel.

      • RSG

        The Beretta cougar is the ugliest pistol Beretta has ever made. That’s why it didn’t sell. And the PX4 doesn’t sell because even the compact and sub compact are waaaaay too fat to even be considered for concealed carry. Other than the many variants of the 92 series, and their elegant 80’s series of .380 Cheetahs (the finest .380s the world has ever seen), Beretta hasn’t designed a decent pistol in 30 years. And this coming from a Beretta fanatic.

        • Andrew

          I feel that the fullsize PX4 is comparable to the G19 in concealability. I’ll have to compare them more closely sometime. When I need something smaller, I carry a Kahr. I do want a Cheetah.

          • RSG

            The PX4 is a brick compared to the G19. Even the subcompact is extra wide, even though that model does NOT have the rotating barrel. The Cheetah is the most reliable, elegant .380 ever made, fwiw. I bought a new 85F in 1992. It ran perfectly until reaching just over 14,000 rounds and everything wore out all at once. I used the slide stop, always, to release the slide. That wore out at the same time I lost the trigger reset. I sent it into Beretta and they replaced the slide stop and all the springs. For free. I also bought a like new, pristine 85FS (updated) in nickel about 5 years ago. Although larger than almost all other .380’s, the gun is the perfect size to fight with (I’ve been complaining at Beretta to build a 9mm in the Cheetah sized footprint for 20 years. The 92M or L compacts are still huge compared to the Cheetahs) God forbid it was ever needed. I still carry it occasionally, but it splits time with my G42 when I carry a .380.

        • HKfan

          I agree, I have lost all hope for Beretta to produce a combat/concealment pistol for 2017 that can compare with Glock or SIG or HK. Their APX is garbage. Their PX4 was a polymer framed 92 with no innovation.

          I would buy a 92FS any day before an APX or PX4.

  • Sean

    lol so clearly, Glock could have started innovating at any time and just decided, nah.

    • When your customers applaud mediocrity, there’s no need to actually pursue perfection.

      Hopefully, the G46 marks a new era of actual innovation for the company.

      • RSG

        Actually- because ALL of the competition is both so far behind AND operates below the “mediocrity level”, Glock (the undisputed world wide leader in handgun sales) has no need to invest resources into new research and development. And no, I’m no Glock fan boy.

        • Michael

          If you think “ALL” the competition is behind the Glock, then you are either and fanboy, or you have never fired another modern design. There are guns that are inferior to Glocks, but there are also many that are better, or at least equal. Glock got into the polymer/striker game at the right time and dazzled the world with hype and marketing. Then they chose not to keep up.
          Name one Glock feature that no other mfg has improved upon, or at least is on par with.

          • RSG

            “Name one Glock feature that no other mfg has improved upon, or at least is on par with”. The ONLY one that matters…….it’s reputation.

          • Michael

            HK pistols, among others, also have excellent reputations. Try again, with something more concrete, please.

          • RSG

            At an average of nearly twice the price. Try comparing apples to apples, instead of oranges. You going to throw nighthawks or Wilson combats into the mix, too?

          • Michael

            No, because they are not really an improvement, imo. I feel that their weight and capacity offset their accuracy advantage.

            HK cost is a good point. However, Glock reputation alone is not a good argument that “ALL” pistols are behind the curve compared to Glock.

          • HKfan

            VP9 weight (unloaded) 25.56 oz.
            G17 Gen4 weight (unloaded) 25.26 oz.

            What weight difference?

            VP9 holds 15, G17 holds 17, I have truly never met any person who has made a big deal over 2 rounds. If the VP9 held 10 or 12, then I would understand but most people prefer the G19, which holds 15. Also, a bunch of people owned P30s and being able to use the same mags is brilliant. HK pistol mags are also one of the few that I know that can be loaded for long-term (2+ years) and still feed reliably 100% of the time. Can’t say the same for Glock mags, especially the early ones that would split down the middle.

          • Michael

            Didn’t show up in the right order on disqus, but my weight and capacity comment was an answer to RSG mentioning custom 1911’s. The comment was not intended to apply to the VP9.

          • HKfan

            got it

          • Michael

            A quick look at Cabela’s shows that a gen 5 G19 is $600. An HK VP9 is on sale on the same site for $580.
            In the same price range as a G19, one can get several alternatives, including a PPQ, XD, M&P, PX4, CZ P07, P09, and lots more.
            If price is your best case for buying a Glock, there are many slightly cheaper options that are very good.

          • RSG

            VP9 is garbage. Makes a fine range toy, has a decent rigger, but it’s not a combat quality pistol. CZ makes fine products, but again, apples to apples. Until 15 minutes ago, they didn’t even make a comparable, striker fired pistol. Let me know in 10 years, not in 10 months, about its reliability. In the meantime, like the VP9, it’s just a range toy. The only striker fired brand on your list is that can claim decent adoption is the SW M&P. And even though there are some advocates that prefer them, industry wide, they’re a distant second to Glock, by a wiiiide margin.

          • Michael

            I guess I just don’t view widespread adoption as a large advantage. I still disagree with your statement that all others are behind Glock. Its not that Glock makes bad guns. I just don’t feel they are the only option anymore, and in my opinion, other brands have surpassed them ergonomically with little or no tradeoff.

          • john huscio

            The wider the adoption, More and cheaper mags, more parts, more night sight/holster choices……..its why i probably wont ever get rid of my glocks…..

          • michael

            My Beretta PX4 came with 2 mags and cost $30 less than a G19 gen 5. PX4 mags are $32 each, directly from Beretta. Factory Glock mags are around $30 each. Same with XD’s and M&P’s. Holster selection is only a problem if you are two lazy to check more than one or two makers. High Noon Holsters sells a full range of excellent quality holsters for every gun I have looked for, except my Kahr (which other holster makers cover) And they do custom work. As for night sights, many non-Glocks are available from the factory with them and most are available from the MFG as an accessory. Glocks are not bad, but there are other options. Ones which fit your hand.

            Widespread adoption is only important if we are discussing truly obscure guns, or if you are a straight-up sheep.

          • john huscio

            Most glocks now come in the box with 3 mags and ive gotten glock factory mags for $20-25 pretty regularly…..lightly used g17 mags frm hkspecialist for $12……..i could walk into a field & stream and come out with a g19 holster…..px4? Walther? Any CZ pistol? Not so much……glock’s aftermarket night sight selection is unmatched…..except perhaps for the M&P….

          • Michael

            You don’t math, do you?
            As I mentioned, a PX4 cost $30 less than a G19 and came with two mags. A mag costs $32. So if I want 3 mags, a PX4 costs roughly the same as a G19. So a G19 coming with 3 is irrelevant. Don’t latch onto the PX4 part too much… this is true for many polymer guns. And some non-Glocks also come with 3 mags. Glock’s night sight selection unmatched? What makes any of those night sights better than any other available for most autoloading pistols?

          • richard kluesek

            and AKs and ARs

          • Machinegunnertim

            Pure opinion, explain why the VP9 is not a “combat quality pistol”.

          • HKfan

            How exactly is the VP garbage?

            “The only striker fired brand on your list is that can claim decent adoption is the SW M&P” This claim is laughable. The M&P has gained little overall adoption. Funny how M&P means military and police yet no 1st world military has ever adopted it. The M&P is a good baseline budget commercial pistol but to compare it quality wise to a Glock or HK is dumb.

            Please respond with an answer to my 2 questions and please do not cut and paste the list of M&P users from Wikipedia. Even if you look at the countries who have a small amount of police using it (Pakistan, Liberia, Lebanon, Iraq, India, Afghanistan) these countries are so limited in money and brains that they go with THE LOWEST BIDDER 95% of the time. I would actaully be embarresed if I was a top dog at S&W and found out that the majority of my M&P users outside the US are in 3rd world dumps Middle Eastern countries.

            France and Italy have a tiny department noone has ever heard of use probably like 9 M&P’s. Big wow

            Now the Glock 17/19, Sig P226, HK USP are prime examples of established guns that have received worldwide, both LE and military, adoption, not middle east shitthole lowest bidder. Even the Walther P99 has so much more LE/military use on the global scale than the M&P

          • john huscio

            Cabelas is hardly a good baseline for pistol prices…..

          • Michael

            My point is that unless you are buying Blue Label, Glocks really aren’t much, if at all, cheaper than the competition. And since other guns are available with LEO pricing, Blue Label is also a wash.

          • john huscio

            Steyr M series has been a revelation for me… rank the m9/s9a1 head and shoulders above anything HK or SIG have released in the past 15 years…

            Glock’s reputation is mainly the result of extremely aggressive marketing (the cost of which is passed on to the buyers) and the large fan base resulting from it.

          • Mikial


          • Mikial


        • I mean, we’re not even talking “investing in R&D” here. They just need to copy the LoneWolf Timberwolf frame, which has been out since 2008, and offer basic features like front cocking serrations and decent pistol sights.

          What makes this so infuriating is that nothing I’m proposing requires any actual effort or innovation. This is simple, open source stuff that’s been available for 20 years, and is very simple to implement.

          They just need to spend the extra 5 Euros in production cost – costs which the consumer would be more then happy to absorb. I’d certainly pay $50 more for a Glock with a Timberwolf stye frame, NP3 coated internals, real metal sights, and forward cocking serrations – as would everyone else.

          But I agree – Glock is the undisputed leader in handgun sales. But that owes as much or more to the incompetence of its competitors over the last 35 years then it does to the superiority of the Glock design.

          • Machinegunnertim

            The more I learn about glocks the more i dislike them. They have the reliability and cheep mags going for them and that’s IT! They have used many years of aggressive marketing to convince the masses that glocks are the best and affordable and “Perfection” total B.S.!

            I’ve handled and fired a number of reliable handguns that had a far more comfortable grip and overall frame, lighter recoil with less flip, more features and they all cost less too!

            Knowing that, why the hell would I guy a Block? Just because several other people are doing it?

            When I ask people why they bought a glock most of them did it because they are mindless followers, or know nothing about firearms and were persuaded by glock’s heavy marketing. Rarely is it a well thought out and informed decision. When it is, it’s because they are willingly ignoring the superior attributes of other pistols and companies.

            Also, every L.E. agency that’s i know of that actually holds tryouts for a new handgun ends up not picking the glock. Recently the Office of Secure transportation selected the M&P over glock and a few others. Several police forces in the U.S. are adopting it as well as the DEA, groups in ,Australia, Canada, Colombia, France, India, Iraq, Malaysia, Pakistan, Puerto Rico, Republic of China, Trinidad, the Belgium Federal Police and probably a lot more as those are form an old list.

      • micmac80

        G46 is strictly a one off project a German LE model (no civilian sales planed) built to make Glock pistol fit the German police requirements, requirements that have so far disqualified Glocks from being used by German police in past decades .Only one using it are GSG9

        • It seems odd that they would need a rotating barrel to allow for disassembly without pulling the trigger; a “decocker” type device on the back of the slide would be sufficient.

          I have / want to believe that the rotating barrel is for some sort of performance enhancement beyond simply a safer takedown method.

          • nova3930

            Exactly. There’s lots easier ways to meet a disassembly without trigger pull requirement that don’t involve a rotating barrel. There’s got to be some other logic tree that drives them to this solution

          • john huscio

            Rotating barrel softens recoil and improves accuracy…….”bbbuuut beretta did it first!” Steyr did it in 1912……and the px4 is hammer fired and has a high bore axis…….im not sure if the rotating barrel system has ever been coupled with a striker mechanism before…..glocks treading virgin territory….

          • Silubr

            The Schwarzlose Standard (aka. “Model 1898”) was a striker-fired, rotating barrel handgun in the 1890s. Nothing new under the sun…

        • john huscio

          Its not a “one off” when glock has given it a model number and has applied for a patent for their new design here…..

      • n0truscotsman

        Many times, consumers see no reason for the wheel to be reinvented. Glock’s reluctance to change what works is a very logical approach.

        But I am genuinely curious about this new design though. I hope it goes far and doesn’t get vaporwared.

        • I’d hardly call “metal sights” and “forward cocking serrations” to be reinventing the wheel. More like improving the tread on the tires.

          Glock is not reluctant to change what works – they are just resisting any change that could slightly increase production costs. It’s a profit over perfection approach.

          • n0truscotsman

            I would love to see forward serrations. Its a common mod people make on glocks.

      • JD

        You morons seem to forget, EVERY polymer framed striker fired pistol is a copy of the glock. It’s the most innovative pistol since the 1911. Yeah it wasn’t the first poly framed pistol, but it was the first one that worked well as the VP-70 is a POS.

        • It was the most innovative pistol – in 1982. But in the subsequent 35 years, Glock has largely rested on its laurels rather then updating their design and staying innovative.

        • Alex

          You tend to forget that Steyr 1908 pistol had similar mechanism Glock has. The Steyr was big, heavy, had no detachable mag, held just 9 weak 8 mm rounds and was no match to other contemporary semiautos. So it became obsolete and forgotten. Somebody at Glock made some improvement and claimed innovation… Genious move! Fact-it worked and sold enormous quantities of an mediocre pistol.

          • JD

            Lmao! What a great story!

          • JD

            Perhaps you should study your history some more, because the glock and the 1908 steyr designs have absolutely ZERO, ZERO in common with each other.

  • Heartbreaker

    The Grand Power rotating barrel is even simpler, just a helical cut on the barrel riding on a roller bearing. My K100 is awesome.

  • Nayden

    46 already? What happened to Glock 44 and 45?

    • Alan

      G44 will be .44 Special/Magnum for the San Francisco PD Detectives.

      G45 will chamber the new 4.5mm “schnell und dumm” round as Glock’s late entry into the varmint pistol market.

    • I’m hoping/praying that the G44 is a 4″/8rd version of the G43, as a sort of single stack G19.

      • Stuki Moi

        43 is burdened more by the thinness of the grip, than it’s shortness. The 36 already is about as slim as a proper fighting gun can be made. Singlestack fighting guns are naturals for the old ACP for that reason.

        Now, a staggered 10 round 9mm, similar to the 36 in size, would gain enough capacity to be interesting.

        • I actually really like the thinness. Aside from the concealment factor, I find they “point” very intuitively, similar to pointing my finger.

          One of the reasons I want the Kahr TP9 Gen 2 5″ to hit the market.

          • Stuki Moi

            Man, you are unusual…..

            Most people, at least that I have ran into, find the micro 9s and .380s to provide about the same grip as trying to hold onto a pencil that fires .44 mag.

  • Polaritypictures Ken

    How can they be awarded a patent on something that already exists? I can name five pistols that used this last century. I smell a lawsuit…

    • The patent alleges a new style of rotating barrel lockup with less wear through repeated use then previous designs. Not a patent on rotating barrels in general.

    • Amplified Heat

      No kidding; 1912 Steyr-Hahn even came from the same nation. Apart from the hammer fired fire control group & plastic frame, the lugs, the camming, even the recoil spring placement are identical. Except uglier.

    • PK

      It’s not a patent grant – it’s a patent application dated Dec 9, 2016 for submission and Jul 13, 2017 for publication. “Publication type Application” couldn’t be clearer, Hrachya simply misunderstood what it meant and that it’s not a grant.

  • Reazione Catena

    I like the idea, I have several Glocks and a few Beretta PX4s, the helical locking barrel is a very sound design. Using the helical locking system it looks like the G46 will have a fully supported chamber as well…

  • mig1nc

    Would be difficult to suppress. Rotating barrel guns have that problem.

    Grand Power has a good suppressor and mount setup though. From what I understand.

    • iksnilol

      Not really a problem, you just need to account for the rearward movement. Just like you need to account for the vertical movement with a Browning action.

      • p672997

        That’s not the main problem. Hint: what kind of motion causes a suppressor to loosen? Last time I checked it was rotation.

        It’s not impossible certainly. B&T has a special suppressor model designed for Beretta Px4 Storm pistols after all.

        • iksnilol

          Rotation is easy to account for.

          Left handed rifling with right handed threads. The more violent torque of the unlocking will tighten the suppressor whilst the more relaxed locking won’t really loosen the suppressor.

          • mig1nc

            Right, but the problem that’s been seen when trying to use thread-on suppressors or mounts is that they can over-tighten and become very difficult to remove.

            Look at the Grand Power suppressor, they use a special barrel profile that takes a mount somewhat similar to the KAC QDC line of cans.

          • iksnilol

            I know, I’ve seen it.

            Difficult to remove is just a case of bad lubrication and never removing the can in the first place. Sure beats a flying can though.

  • 2wheels

    I’m curious as to why they departed from their tried and true lockup method? Nothing wrong with rotary, I’ve owned a Cougar and it was a solid gun, but there has to be something causing them to totally depart from the norm. I expect it from Beretta, they like to be different. But Glock? They hate changing their basic formula.

    Also, why does everyone immediately jump on the suppressor thing? Who cares? Not every pistol needs to be suppressed, especially if it’s meant for a police contract.

    • LGonDISQUS

      The market for non glock brand glocks is beyond cottage industry, like it’s a legit career making parts, frames, slides, barrels or 80%’s.

      Glock could go out of business tomorrow and no military or police force would be worried since they could always get parts from the third party player for, like, an eternity.

      • Andrew

        Non-Glock frames are the best Glocks money can buy.

        • LGonDISQUS

          I have yet to buy a glock. Really should, but eh….

          I like .380s like life, but that NATO standard calls me. (Along with 5000 rounds in my safe and only wrecked PF-9. [rust])

    • iksnilol

      How many layers of German engineering are you one?

      • MeaCulpa

        About one I’d say, the roller-delayed blowback is, kind’a, a German thing, the Glock is Austrian and the 6.5×25 is Swedish. My plan for the USMC to adopt silenced M/98s , Lugers and MG42s is way more Germanic (and also a better plan than the “let’s ditch the SAW and wiggle out toes” plan that is currently in play).

        • Brett baker

          You will ban checkmate from supplying the Luger mags, right?😉

          • MeaCulpa

            Only polymer Magpuls allowed! We can’t have multiple suppliers of magazines messing up our logistics can we? And I’m sure that a sufficiently motivated marine can make it fit with some elbow grease and bootstrap pulling.

  • Gregory

    It looks like it has the wide slide of the model 20/21 to accommodate the locking mechanism. Count me out because one of the things I like about the model 17 and 22 is the narrow slide. Everyone else is going to wider and wider slides which is unnecessary.

  • Squirrel

    Im curious how it takes down at all. No slide lock in the images.

    • Know_Your_Subject

      The German article seems to say that the back plate includes a mechanism for takedown.

  • b. griffin

    And the G45???

  • b. griffin

    BTW: A rotating bolt ought to make it more accurate.

  • Anonymoose

    So we’ve gone from everyone copying Glock, to Glock copying Beretta. They skipped a couple numbers though. Where is my single-stack .40 and .357 (or 10mm?!) Glock? Glock SMG? Glock rifle?

    • Sledgecrowbar

      The number does suggest there will be other models coming soon.

    • BattleshipGrey

      My guess is that they’re trying out the 9mm version of the rotating barrel since 9mm is standard for LE in Europe and if they can slide in on HK’s market, good.

      I noticed that in the pics above, the barrel appears to be fully supported, which makes me hopeful for stouter cartridges like .45 Super and such for the G44 and G45. The skip to G46 is interesting.

    • Patrick Reginald

      Why would anyone want a single attack .40? Its a dead caliber, don’t hold your breath.

      • RSG

        Lol. I posted the same thing as you before reading the comments.

      • 2wheels

        I began to notice this a few months ago when used pistol shopping, there were soooo many used .40s sitting in the display and precious few 9mms and .45s.

        That kinda says to me that people are dumping their .40s much faster than any other caliber.

        • Patrick Reginald

          All you have to do is look at what fawdy offers, and that is more recoil with less rounds. Not really a great trade off haha

      • Joby

        I said this somewhere else in the comments, but it’s something a lot of people don’t notice so I like to share it when I can. There are 2 things 40 is good at: IDPA bunnyfart handloads, and short barrel power. Out of a 2 inch barrel it matches the .357.

    • RSG

      Since the world has already determined that 40SW is no longer a viable cartridge, I’ll venture to say the single stack .40 Glock you’re looking for is coming…….never.

      • DiBs

        Meh. I don’t like the .40, but many people do. Glock’s in .40 cal are issued, with no other option, to LEO’s in all but one agency in my area.

        Larger calibers than 9mm are one magazine capacity restriction away from a resurgence in popularity.

        • john huscio

          How popular is .40 in california or NJ?

          • DiBs

            Not a clue. I avoid CA as much as my job allows, and I have never been to NJ. The .40 is quite popular in the Southeast, though.

          • DiBs

            During the Federal 10rnd days, mag capacity limits were often cited as a reason someone liked larger calibers.

      • Anonymoose

        Perhaps it will be a single-stack .45GAP then. .40 is still popular with a lot of normies and police departments (minus the FBI). It’s also just a barrel-swap away from .357 SIG (or .357 Auto as Glock likes to call it), which is a measurably better cartridge than 9×19.

      • Joseph Baumann

        Which sucks because .40 is really well suited to short barrels. Out of a 2 inch barrel its nearly identical to a .357

        It’s the one thing where .40 really shines.

  • Sledgecrowbar

    I wonder if they could use the new striker design with their existing action. It may have made the difference with the MHS competition, even though their frame isn’t modular. I hope it’s not a bad trigger.

    • Andrew

      The only thing that would have helped Glock in the MHS would have been to be a Sig.

  • crazyXgerman

    Love the German term for the mag release in the graphic:

      Love the accuracy of google translate /s

      • Silubr

        The term Glock uses does sound awkward, though (like a literal translation of “magazine release button”). The more common term, I guess, might be Magazinhalter or Magazinhalteknopf.

  • Alex A.

    I like the trigger redesign and ambi slide release.
    So what’s the point of this new system? What are some more advantages to this besides parts being more durable to wear than older glocks?

    • ostiariusalpha

      The parts are not more durable to wear compared to the previous tilting breech Glocks. The claim is reduced wear compared to past rotating barrel designs by other companies (e.g. Steyr, MAB, Beretta, Grand Power). The point of locked breech, rotating actions is to keep the barrel aligned with the slide for improved consistency and better shot precision. There’s also very slightly reduced muzzle flip versus a tilting barrel; and the bore axis is generally lower on a non-tilt action, which also reduces flip.

      • Tassiebush

        Gee you’d really want to make sure the thread direction and barrel rotation were compatible!

        • ostiariusalpha

          Yeah, rotating actions are only a little bit better than tilting actions for suppressors. As far as recoil operation is concerned, dropping block actions are better than either, such as on the Walther P.38/Beretta 92 or the Arsenal Stryk series. Delayed blowback and hesitation lock pistols are the best for hosting suppressors, since the barrel doesn’t reciprocate; that’s why SilencerCo went with delayed blowback on the Maxim 9, and why the Remington R51 was even more of a disappointment than just as a failed pocket pistol.

      • Alex A.

        Thanks for the great info! I was just going off of the Glock patent’s claim that it was more durable. Yet I couldn’t see all that trouble of redesigning just for that. So if given the choice, which design would you choose?

        • ostiariusalpha

          I mention elsewhere that drop lock actions are better for suppressor use than either rotating or tilting barrels, so probably a Beretta 92FS for 9mm ammo. Of course, if you can get a hold of an HK P9S in good condition, you’d be even better off; or an HK P7 would work nicely as well. Either of these delayed blowback HKs can be found chambered in .45 ACP also.

  • Shawn M

    One striking difference that I did not see mentioned (perhaps I missed it) is the trigger assembly.

  • Rabies

    A rotating barrel would make it possible for a lower bore axis.

  • frittb

  • Giolli Joker

    Finally something actually new in Glock’s lineup…


    Well, call me a skeptic. I’ll hold comments until early adopter comments are chucked like chaffe from the wheat.

    This is just a touch out of my realm of knowledge.

  • Dan

    This, the gen 4, and the gen 5 are just making my Gen 1 17, gen 2 19, Gen 2 17L, fish gills 17, etc. collection more valuable. Thanks Glock, for not being able to leave well enough alone!

    (Also, I predict a stupid proprietary suppressor mounting system with lugs or splines)

  • Змейго Рыныч

    Told it Steve last tuesday, but no reaction. The “key” to disassembly is attached to the strike, but easy removable. The bore axis is lower. The beavertail is longer. The bore walls are thinner. No more unsupported chamber due to rotating bolt.

  • glasspix

    The only thing I am interested in is whether it is going to have an orange follower.

    • john huscio

      Its in the picture

  • Strongarm

    First, the patent application is not granted, it is simply published as crossing the necessary time pass according to the new regulations.

    Most noticable feature seems, the lack of disassembly latch. Pistol looks as field stripped by
    barrel rotations like early blowback FN striker handguns.

    Patent application seems containing limited explanation about the full lenght of slide. This might be an indicaton for further applications concerning about disassembly without dry fire. However the slide underside reveals a different lock up at extreme rear for half cocked striker.

    An interesting and different approach seeming no future.

    • Strongarm

      See also the patent application; US 2017/0227313 A1 which describes a different disassembly latch which seems absent in German Magazine photo sample.

  • PK

    Below are some images from a US Patents (US20170198993A1) granted to Glock in 2017.

    That’s an application, not a grant. This is, at best, a very slight iterative improvement on prior art dating back a century.

    • Hrachya H

      Thanks for pointing that out. I didn’t notice it. Fixed!

  • Some Guy

    I don`t see why this should be for the German police most of the 16 police units, the federal police and other LE agencys already have guns that are realivly modern(Sig P229, HK P30, P10, VP 9/SFP 9 and P2000 or Walther P8 and Walther P99).
    The only ones to replace their old guns are Bavaria, Saxony, Berlin and the Polizei DBT(They have either the HK P7 or the Sig 225 because of their capacity). Bavaria, the biggest police agnecy after the federal police, already is searching for a new gun(the Walther PPQ, the HK SFP 9/VP 9 and the Sig P320 are in the running). The other are not really big enough to develop a gun for them when they just need a higher capacity pistol(Bavaria has more than 42000 working for the police the other three with old guns 37000 together).

  • Jean-Raymond Daubresse

  • Harry’s Holsters

    I don’t like the look of the beavertail. If these become available in the US I’ll grind it off with my belt sander but I’d still rather not go through that process.

  • armatus rebellio

    Something just don’t look right. Fully supported chamber. No feed ramp. Extractor position in slide (height) relative to the bore axis. That’s a LOT of (particularly needless?) innovation on Glock’s part. More than has ever been seen since the beginning of Glock-time. Seems UNGlock. Is Gaston in hospice?

  • Iblis

  • Mike Cramer

    Where’s the 44 and 45?

  • Tim

    That’s one way of getting around the issue of locking blocks failing.

  • Cyrus Freeman

    The first thing that jumps out at me is that the bore axis seems unchanged even though rotating barrel lets one drop it by a few mm. The second thing is what are the G44 and G45?

    • Blake

      That’s what I was thinking. Of course Glock would introduce something like this and completely butcher it.

  • HKfan

    G19 has set the standard for the compact carry pistol only because it has been around since 1988, Glock’s bombardment of marketing, 100,000+ companies making Glock accessories, and Glock always prices their guns 10-30% lower than competitors.

    but the high bore axis comment is stupid. It was made by people who think they know science to knock on competitors because they have nothing other to complain about. I have VP9 and it has the same recoil as G19. My P226 feels as it has less recoil than my Glock even with the mile high bore axis.

    There are many guns that come within 1/2 of Glock 19 and have same capacity: Sig P229, PPQ, P320 Compact.

    M&P sales are horrible. They are blowing them out because they can’t get rid of them. The fact that it took S&W 11 years to make a G19 sized M&P says a lot.

  • Mikial

    Yet another reason to love Glocks, as if I needed one. Yeah, go ahead and flame me for being a ‘Glock fan boy,’ but I carried one in Iraq and I carry one daily here in the USA. They never failed and I know they never will. I like a lot of guns, and my 1911 Commander is more accurate, but I still carry my Glock.

  • richard kluesek

    At least they remembered to contour the front of the frame to match the shaping of the front of the slide. Front cocking serrations will be requested.

  • cbunix23

    I assume a suppressor on this would not work well, or at all, because it would add weight to the barrel and prevent it from rotating at the correct speed. Is that right?

  • Isn’t this basically how the Arsenal pistol works?
