BREAKING: M17 Modular Handgun System ACCEPTED for Service by Navy, Marine Corps, Air Force

Image source: SIG Sauer

The US Army’s M17 Modular Handgun System, derived from the SIG P320 handgun, has crossed one of the final hurdles on the track to full replacement of previous service handguns (including chiefly the Beretta M9). The United States Navy, Marine Corps, and Air Force have all announced their acceptance of the M17 MHS as the new sidearm for each respective service, according to a story written by Matthew Cox for KitUp!

The Modular Handgun System competition was decided with an announcement in late January that SIG Sauer had beaten out FN, Glock, and Beretta for the massive $500 million dollar contract for future 21st Century US Army sidearms. A protest on the decision from Glock is still pending a Government Accounting Office (GAO) ruling, which is expected by early June.

The M17 MHS is a derivative of the SIG Sauer P320 handgun which sports interchangeable grip modules, suppressor support via a threaded barrel, interchangeable slide lengths on a single frame, and an integral optics mounting plate. Departing from the complex double action/single action hammer fired mechanism of the previous M9 pistol, the M17 Modular Handgun System utilizes a much simpler and cheaper striker fired design pioneered by the famous Glock family of handguns and utilized by SIG starting with the P320.

    Welcome to the striker fired modular sidearms era.
    Sig P320 seem good gun but civilians want probe the M17.
    In 15 years, will everybody return to DA/SA handguns?

    • No. DA/SA offers significant technical disadvantages over either a striker or SAO design.

      • CommonSense23

        I’m a DA/SA fanatic but no military or police force is going back to it. Way to many negatives in the training alone for that.

      • 8166PC1

        I think it’s more complicated than that. It’s much easier to have an accidental discharge with a Glock type striker fired pistol than a DA/SA. Heavier triggers on pistols are safer overall.

  • NukeItFromOrbit

    I am very pleased with the military’s choice of the M17, my only complaint is they didn’t go with the .45 caliber variant as was the plan for one of the handgun replacement programs preceding MHS. I know the whole NATO standard argument but pistol ammunition must represent an incredibly small part of the greater logistics picture. Among American infantry I think there is more confidence in .45 and considering how rarely handguns are used confidence in the weapon is very important.

    Yes I fully expect the 9mm corner (no offense) to tell me how 9x19mm is God’s greatest gift to mankind and the perfect pistol caliber by which all others must be judged.

    Or bring back 10mm.

    • Matt

      Stopping power isn’t the reason 9mm gets chosen over .45.

      • nova3930

        Yep. 9mm is generally considered a better compromise among all the factors you want in a pistol ie size, weight, capacity, power.

        If I could get a 45 that was the same size, weight and capacity of a 9mm I’d darn sure take the 45 but that’s just not physically possible.

    • No one

      “Yes I fully expect the 9mm corner (no offense) to tell me how 9x19mm is
      God’s greatest gift to mankind and the perfect pistol caliber by which
      all others must be judged.”

      Isn’t that what .45 ACP and 1911A1 fanboys always do?

      I guess “god” in this case must be “The FBI” who kind of proved there’s no real difference in performance between 9mm Luger and .45 ACP but quite a few downsides.

      • Sunshine_Shooter

        What you just pointed out is what people call “projection”, the act of attributing to your enemies those flaws which are present in yourself.

      • NukeItFromOrbit

        You mean that one time the FBI wanted a whole new caliber because 9mm wasn’t cutting it and and .45 was too heavy and they ended up with two new calibers?

        The fact that they later went back to 9mm is yet another story in the incompetence of government bureaucracy. Might as well let FBI agents pick their own weapons.

        • Blake

          “the FBI wanted a whole new caliber because 9mm wasn’t cutting it”

          If you’re referring to the birth of 10mm Auto & .40S&W, the FBI project was to replace their .38 Special standard revolver load after the 1986 Miami shootout: https://en.wikipedia.org/wiki/1986_FBI_Miami_shootout

          9mm defensive bullets & handguns have come a long way since 1986.

          • You are partially correct, but 3 of the 8 FBI Agents were using S&W 459 9mm pistols. The two who died were using 9mm so it’s effectiveness was very much in question as well. Though 9mm hits on 1 robber were later deemed by the medical examiner to be “fatal” the rounds did not stop the robbers from continuing to shoot the agents. I agree that 9mm today is far superior to what they were using back then.

          • Blake

            Right. However part of my point was that there’s a big difference between 9mm in 1986 (heavy/bulky S&W 459 & probably FMJ bullets or basic hollow-points if they were lucky) & 9mm now (e.g. Speer Gold Dot, Hornady Critical Defense, etc.) & the plethora of excellent handguns available (especially for CCW, which was pretty much revolver-only back in the day).

          • Very true, and I agree 100%.

          • Robert Kalani Foxworthy

            and 9mm in big army can still be only 9mm ball soo…

        • No one

          You mean that one time most of the FBI were still using .38 Special revolvers and contrary to popular belief, only a few agents had 9mm loaded with the rather poor performing Winchester Silvertip bullet designs?

          Yeah, let’s just ignore the massive amounts of actual tests, trials, and collected data from field agents they gathered when they went back from .40 S&W to 9mm Luger and even publicly stated there’s no difference in actual real world effectiveness in 9mm Luger, .40 S&W, and .45 ACP, but showed the downsides to .45 ACP were rather massive. and pretty much countless other tests and real world scenarios that ultimately pistols in pretty much any caliber are bad at stopping a determined attacker no matter what the caliber (Hint, firing a slow bullet that makes measuring temporary cavitation meaningless and creates no other remote or direct wounding effects will leave you disappointed). It’s all just bureaucracy because you said so!

          Oh no, wait, That’s just a way for you to cop out of a losing argument, you started the argument, I countered, the burden of proof is now on you to show that .45 ACP is actually any better with real world data and testing.

      • Wow!

        The FBI showed that there is no real difference in performance of 9mm and 45 when they are in hollow points. The military is not using hollow points (but they should). 45 does bring a significant advantage over 9mm. Consider that a 9mm hp expands to around 40-45 diameter. That expansion is done for a reason.

        • No one

          Hint: there’s also no real difference when both are using Ball rounds, but all the downsides of .45 ACP pointed out still exist, unless you think a (quite a bit) slower, 2.5mm wider ball round is going to make some massive difference in performance. (It isn’t, at all.)

          Also, Good 9mm JHPs can expand to in excess of .60-65, where you got those numbers is rather baffling, but yeah, there is a reason, pistol rounds are awful and JHPs just make them go from awful to mediocre against stopping a determined attacker.

          Please don’t try to lecture me on topics I’m more then versed about, thanks.

          • Wow!

            The diameter that a 9mm expands depends on how deep the cavity is made (which varies, and why I said around 45/40 diameter), and often if you get too wide, there isn’t enough material at the base of the bullet to keep the petals intact. A fragmented petal is not as effective as a solid bullet because while it will cut through ballistics gel, it is often stopped short in an actual body (since gel is somewhat of an exaggerated depth of a real body in order for differences to become more apparent. Hollow points don’t expand that frequently in real life. The reason the 45 is more desirable is that in its expanded form it already is wide enough to promote faster blood loss, and if it is in hollow point and does expand, it is just added bonus.

            Both projectiles have enough energy to punch through a person, so penetration is not an issue. Assuming cost and training is negated (after all, cost goes down with prevalence and training should not be the limiting factor in selection, especially since a shooter should be proficient enough to use a 9/40/45)
            It is hard to say that the 45ACP has disadvantages that the 9mm doesn’t. If anything, both cartridges have similar disadvantages (low energy, heavy weight compared to rifles, etc) , but the 45 suffers less due to its larger diameter.

            There is enough of a difference in diameter that many departments did not utilize the 355 subcalibers for anything beyond pocket guns until better hollow points started becoming more prevalent. Until that period, a lot of focus was pointed to the development of a supersonic 40 caliber.

            Also your argument is not bolstered by asserting a position of authority. Hiding behind a non-existent authority often means you lack the knowledge to defend a previous assertion.

        • redsr

          But the 45 acp you can’t get larger than single stack and have the ability to run universally sized grips… Also, while 45 ACP is arguably superior to 9mm in ball for indoor use (subsonic being part as well as greater diameter), if looking at 25+ yards, the 9mm is clearly superior due to being flatter shooting and intrinsic accuracy/capablity advantages due to lighter recoil, faster followup shots, and greater capacity.
          Pistols in the military are either last ditch weapons or enough weapon to fight to your rifle. For neither purpose is ballistic potential of the round the primary consideration — which was what the FBI’s study examined.
          And for these pistols, Sig partnered with Winchester to provide hollowpoints to US soldiers, pending JAG approval. The US did not sign provisions of the 1899 Hague Convention related to expanding bullets.

          • Wow!

            45 ACP is available in double stack. Compare a G21 to a 1911, there is very little difference in width. The main reason the 1911 feels better is because it has a concave to its sides, vs the glock which is more square. S&W M&P got around this with grips that swell at the point where the middle of your palm meets.

            Agreed, we should start using hollow points.

    • Big Daddy

      You answered your own question. “considering how rarely handguns are used’….45ACP does a better job than 9mm with ball ammo and since a hit with a 9mm is better than a miss with a 45. Considering the lack of training the DOD gives the troops with handguns and the fact there are a lot of smaller men and women in the service now the SIG 320 in 9mm is the correct choice. We don’t use SMGs anymore and there are much better choices for the 9mm than ball ammo now.

      • CommonSense23

        45ACP does no better with ball than 9mm. They both perform terribly.

        • Sunshine_Shooter

          So I might as well have as many as possible, right?

          • Bean Guy

            Nah man, we need to limit our magazine cap to 10+1. If 11 isn’t enough, train more!!!

            – Fudds all over

          • CommonSense23

            Yep.

        • Big Daddy

          Yes they are terrible but one is more terrible than the other. 45 does make bigger holes and both penetrate pretty well on people without body armor.

          • CommonSense23

            I have seen multiple people shot and killed by both subsonic 9mm ball and 45acp. Many times with both rounds being used at the same time on individuals standing next to each other. Could never tell who got hit with what until the debrief. If 45 actually worked better, why aren’t we seeing real world results.

      • Phillip Cooper

        Please provide evidence for your assertion that there “are a lot of smaller men and women in the service now”

        Being that the species is noticeably getting larger, and Americans tend to run to the bigger side of it, I would like to see a source for this assertion.

        • Big Daddy

          Living right near Ft. Hood and having been in the army seems pretty good to me. All I see all day here are people in the Army. This is Cav territory and still there are a LOT more women than when I was in.

          Having been in war we took a lot more people than normally and have also dropped a lot of physical requirements. I think they call them POGS now we called them REMFS. Support people, same can be said for police agencies and fire departments, this is fact.

          One reason the FBI dropped the 10mm was because of smaller men and women in the FBI.

        • redsr

          Women in combat roles. Gender equality. Drop mic.

          • Phillip Cooper

            Ah, in other words, complete BS.
            I keep waiting for one of these pathetic trannies to get crowned Miss America or some crap. You know it’s going to happen.

      • NukeItFromOrbit

        Big Daddy with that sort of logic we might as well go to 5.7x28mm, no?

        • Get over it fanbois

          I myself am a fan of 5.7mm and as cool as it would be. The answer to that would have to be a big fat NO due to the NMH syndrome the defense industry contracted about more or less fifteen years ago.
          Excluding exceptions like the IAV Stryker and the G28.

          • No one

            I think there’s bigger issues with using the 5.7x28mm than that.

            Price for a weapon you’ll barely use in a combat scenario (being that the FiveSeven would almost certainly be the top contender for this) and the fact the FiveSeven has an inherently large grip size, which the Military and many LEOs do infact care about for smaller handed soldiers would be an issue.

            The latter is harder to solve because 5.7x28mm is inherently long for a pistol cartridge so it;s always going to need a relatively large grip. (well, technically a PDW cartridge later adopted for pistol use, but I digress.)

          • ostiariusalpha

            The Five-seveN pistol is now the standard issue sidearm of the Belgian military. They have a crap ton of Hi-Powers though, so the transition is going to be over quite an extended period of time as they wear out the old guns and use up their stockpile of 9mm. The 5.7x28mm has always been a pistol cartridge, it was designed as such from the beginning; it just has a bottleneck case to increase the sectional density of its bullets.

      • Robert Kalani Foxworthy

        but army still can only use hollow points.

    • CommonSense23

      The only reason there might be more confidence is we haven’t been using 45 in GWOT. Had we had people would be complaining about it also.

    • Malthrak

      .45acp is never going to come back as the military standard cartridge.

      It’s just not.

      It’s heavier and more expensive to produce, has a lower capacity to 9mm, nobody else relevant uses it (pretty much just 2nd and 3rd rate forces using old US leftovers), and there is no data showing it is appreciably more combat effective. There is no trauma surgeon on earth who could tell the difference between a wound caused by, or offer a variance in chances of survival between .45 and 9mm. The pining for .45 is nostalgia, nothing more.

      10mm, while a more powerful round, is even more expensive, with a more limited number of platforms and suppliers, with severe controllability issues, and no military anywhere uses 10mm. There is a reason for that.

      Is 9mm the “god” round that beats everything in every way? No, but its acceptable combat ability and magazine capacities coupled with its logistics backing makes using anything else, from a general issue military perspective, a pointless pet project rather than a legitimate military need.

      • Blake
      • Independent George

        9mm kills the body. But the .45 kills the soul…

        • Phoenix 731

          Someone’s been watching Colion Noir’s channel.

      • steve2insd

        Stating that there are no trauma surgeons that can tell the difference is ridiculous.

        • No one

          Really? show me these mystical surgeons reports on the matter that can tell 1, maybe 2mm in difference eyeball wise that can tell a difference if that.

          I’ll wait.

      • Sal F

        .45 is not going to come back, because it just is not the right round.

        – Off the bat, logistics/procurement would be a mess. We have WAREHOUSES of 9×19 NATO. All out allies use it.

        – 9mm is easier to shoot (and not just for women). For 99% of the military a pistol is a defensive last resort, so they want people to be able to hit with it.

        – .45 is to SLOW. As body armor become more and more prevalent (even among the tent dwelling jihadis), the need for a decent AP pistol round is evident. Who knows, maybe in the future, even 9mm wont be enough (though some steel/tungsten core +P+, like the Russian 7N21)

        .45 might still be kept around for NOW in the suppressed role, for when you need something truly quiet, that can still hit with decent power – of course this is really only of use to the SF/SOF guys. Though, with SOCOM tacking a serious look at a .300BLK PDW, I think the .45’s service days are numbered.

    • John

      >my only complaint is they didn’t go with the .45 caliber variant as was
      the plan for one of the handgun replacement programs preceding MHS.

      So the good thing is, instead of endlessly complaining about it, you can fill out a form, get the parts together, and create your very own DoD approved .45 pistol!

    • Get over it fanbois

      I expected tons of 45 fantards to be butthurt but the amount of it is palpable. Hornady and medical examiners have proven the 45 superiority meme to be a load of bull.
      The fantards need get over their damn nostalgia.

      10mm is great for those with an unlimited budget.

    • int19h

      “American infantry” has been using 9mm handguns and subguns (MP5) for, what, just over 30 years now? I’m pretty sure the vast majority don’t even know or care about .45 ACP.

    I wonder how long until we see M17’s on shelves? Thry’ll probably be priced at a premium, but I would prefer this to the P320.

    • it’s P320 with a cutout for an RMR and a thumb safety, in tan, with a slight variation of the trigger guard. I have a P320 with a thumb safety sitting in my shop right now. Doesn’t have the RMR cut, the color, or the trigger guard, same gun otherwise.

      • Phillip Cooper

        There is supposed to be a P320RX which features the optics plate, but it hasn’t hit the wild yet.
        Looks like $850. That’s actually ABOVE MSRP I saw a few months back:
        http://www.cabelas.com/product/SIG-Sauer-P-Pistols/2358450.uts

        • There’s the P320 Romeo series. I’ve had a couple come through the shop already.

      • Flounder

        The hardware (mag release, slide stop, and who knows what else) is a different color than available from the factory.

        And aren’t these supposed to have night sights?

        • Sunshine_Shooter

          Red dots are the best night sights known to man. Well, besides a weapon mounted flashlight.

          • Major Tom

            For best results, use both.

        • So do the stock P320s re: night-sights.

      • J.T.

        I can’t tell a difference in the trigger guard by looking at the pictures. What is most noticeable to me is that they took the full sized frame then shortened the dust cover/rail for the M17 so compact slides could be used on it as well.

        • nova3930

          They already sell that. They call it the “carry” frame. I’ve got one laying around somewhere…..

          • The three rail slots are a dead giveaway for the Carry grip module. The Compact grip module has four slots.

        • That’s the “carry” variant. I have one in my shop. Short frame, full grip.

      • Keith Sears

        The new p320 x series addresses the RMR plate. Scheduled for release this summer.

        • …Or you can get the P320 Romeo series, with the red dot already built in.

    • Sid Collins

      What is the difference if any?

      • Xerxes036

        FDE in color, ambi frame mounted safety, and a “tamper proof” takedown lever so the average soldier can’t take the chassis out of the frame. There may be more differences but I can’t think of them at the moment.

    • Joshua

      The only difference is the slide plate for optics.

      You can get a safety model from Maryland.

    • JT303

      I thought somebody mentioned that Sig said that they weren’t going to be selling the P320 in M17 spec to civvies. I may be wrong there, but I wouldn’t hold your breath for a shiny new M17.

      • Independent George

        Why wouldn’t they? It’s basically a license to print money.

        • some other joe

          Because they’ll have their hands full producing for the contract for the next year or two. With Customs (or BP or all of ICE…) and the rest of DoD jumping onboard, I’m not sure we’ll se production surplus for awhile. Let them get the initial fieldings done and then they’ll start selling when they drop to sustainment production.

        • JT303

          I really have no clue. After all, Beretta sold the M9 to civilians, didn’t they? I couldn’t tell you why Sig wouldn’t put the M17 on the shelves, but I for one don’t think people would say no to owning one, even if it was just to say ‘I have the military one’

        • Xerxes036

          The Contract gives the Army total control over the M17 version of the P320 even SIG has no idea when the M17 will be commerically available.

  • Major Tom

    And thus we begin the SIGening.

  • Uniform223

    This will make logistics across the services just a tad bit easier. Now if only they would go back to having the same style uniform and camo pattern like back in the good old days.

    • Wouldn’t that require that we stop fighting in places that are sand colored?

      • CommonSense23

        Its more I think that he means the services all stop having indivdual uniforms.

      • Blake

        Sounds like a good plan.

    • USMC03Vet

      Bring back woodland BDU! I’m fine with the different branches having their own uniforms and that is due to tradition and regulations, but anything war fighting should be standardized camo pattern.

        Ah… two pairs of uniforms. Woodlands and Deserts. Do I really need Dress Blue Alphas, Bravos, Charlie’s, Delta’s, Service Alphas, Bravos, Charlie’s, one white round hat, one green round hat, one floppy hat, couple of shiny shoes ready for wear at all times? Nope. Maybe the military should focus it’s efforts on lethality and practicality. Let’s make warfighting our heritage, not this pog crap that we’re passing off as tradition.

        • Wow!

          The day when political correctness gets out of our military and police is the day we will go back to pragmatics dictating form.

        I agree the soldiers need to wear the same battle uniform. All of the different cammys are gonna get folks hurt in combat . All I had when I was in was the OD green. And in the jungle uniform they worked. I did not care for the regular fatigues . The pants and ball cap were terrible.
        And when I was in I liked the old 1911-A1. Today being and old sick man with arthritis in my fingers and hands I can’t pull the slide on them. So I have switched to the smith M&P compact with full size mags and in 9 mm. It is eaiser for me to Handel as the slide is not as hard to pull and recoil is eaiser for my hand.

          I never cared much for patterns. OD green is a deceptively effective color in the forest, as are other flat drab colors in their respective environments. Personally, if you need depth in your camo, there is nothing that beats a half ghillie. Even store bought ones are good enough in the general use.

      Very much agreed. The X-Frame removed every complaint I ever had about SIGs. It felt more like a CZ-75.

      Now just get APEX to release that prototype 320 Trigger kit they were displaying at NRAAM and the 320 is nearly the ideal pistol.

      • The Grayguns P320 trigger is better, and is already on the market.

        • Flounder

          To be fair… Quantify better? The grayguns trigger requires a spring and pin change and is 100$ where the apex is 45$

          And the Apex curved trigger is on it’s way. The flat faced trigger dropped a while ago. I don’t know how long, but it was covered here.

          • 1. It is production legal in curved configuration, and will be production legal in the flat configuration once the X5 is on the Production list.

            2. It has an adjustable over travel stop.

            3. It is supported by a company that has been working with SIG on the P320 since nearly the beginning of the P320. The P320X5 is heavily influenced by designs made by GGI, through input by members of the former Team SIG.

            4. The design has been tested through hundreds of thousands of rounds by members of the former Team SIG. Across dozens of pistols, so he has encountered and dealt with most variations of the P320 frame modules and trigger bars.

          • Flounder

            Excellent comment.

            I am curious as to How it has an adjustable over travel stop? I dont see any screws on it?

          • Adjustable probably isn’t the right word. It is set via an over travel surface, as such they didn’t have to design the trigger with a complete maximum of over travel, and instead it can be fitted to guns that may need more trigger travel.

            Through the 3 years I was with the team I saw a variety of prototypes, each one designed to fix issues we encountered with the variations of parts dimensions we encountered. The replacement sear housing pin is an example of the things GGI found in the process. I personally shot 35,000 rounds through the guns before I got the final production parts just before the team was disbanded.

            Anyways I no longer have a relationship with GGI (as I am shooting in division where the 320 wouldn’t be competitive), I simply am supporting them because they put out a great product.

          • Sunshine_Shooter

            Sounds like TFB should do a product spotlight on the GGI P320 trigger. It really does sound like a better product.

        • Ebby123

          I thought that was more of a service – like a custom trigger job rather than a drop-in product?

          • The GGI PELT triggers were released late last year. Some fitting may be required, but it should drop in most guns.

            The competition package is still a custom trigger job only even though it they use much of their own parts. Those parts may make their way into a gunsmith level parts package, but I doubt that they will ever be drop in. I’ve never seen a true competition level package with consistent results that didn’t require some fitting.

          • Ebby123

            Thanks for the info. I had also heard people raving about the Gray Guns competition package.

  • GrumpyCATMGuy

    I can’t remember which LEO dept. on the west coast had issued these, then on the first day of quals with them a few had split/broken frames, and when the dept. contacted Sig about having them replaced, the reply was, “Oh the P320 was designed to work even with a broken frame so that’s normal.” And then wouldn’t replace the frames.

    The next day they were banned from usage within the Dept. I want to say it was Spokane or Portland or Seattle or something.

    As for the DoD jumping on the bandwagon, having shot one of these and was woefully underwhelmed; had quite a few failures to battery and light-strikes on anything CCI/Blazer/S&B/Fiocchi….makes me think of another Sig backroom deal, this time one of the biggest examples of graft by the procurement office in recent history.

    This thing is a high-bore-axis turd, and I really would recommend the DoD/Army/US.Mil look at literally any other modern pistol (Glock 19 Gen4, S&W M&P M2.0, CZ P10, HK VP9, hell even the Canik TP9 is a hell of a lot better pistol than the P320….). Oh that’s right, those other companies listed aren’t really known for greasing palms.

    The trials established, to those within the procurement office, they all must hav had that moment where “Hmm, when I hold the Sig P320, I feel my private bank account getting heavier, more reliable and weather resistant. Must be the right choice.”

    To those of you jumping to the P320’s defense, assuming you’ve already bought one, have you shot any of the other pistols I’ve mentioned? (as in actually ran a course of fire with one, and not just stood there and slowly emptied a single magazine). Seriously, shooting one reminds me of a hi-point. Same kind of trigger, same kind of muzzle-flip. It felt like an eternity waiting for my sights to level back out again.

    The DoD will realize its mistake, though unfortunately it’ll be balls-deep into that $500 Mil. contract before it does.

    • “Oh that’s right, those other companies listed aren’t really known for greasing palms.”

      To quote an inteview with Paul Barret (Author of Glock: The Rise of America’s Handgun.) http://www.npr.org/2013/02/01/170752391/how-the-glock-became-americas-weapon-of-choice

      “[Glock]
      was smart enough to hire a genius salesman. … This man Karl Walter
      was really a guru in figuring out how to appeal to the police β€” whether
      that meant offering them extremely attractive financial terms or hosting
      police procurement officers at [a famous strip club] in Atlanta. This
      was a guy who could make a deal with anybody and figure out how to sell
      the Glock.”

      I also have my doubts a company like HK would have become as prolific as it is without offering some rather attractive deals to many customers.

      That’s not to say SIG’s pistol is the best. I frankly wouldn’t have a clue.

    • nova3930

      The “frame” is a $50 MSRP replacement part. Probably less than half that on blue label for a PD. If the story is true, SIG should have replaced them but overall it’s not that big an issue.

      “To those of you jumping to the P320’s defense, assuming you’ve already bought one, have you shot any of the other pistols I’ve mentioned? (as in actually ran a course of fire with one, and not just stood there and slowly emptied a single magazine). Seriously, shooting one reminds me of a hi-point. Same kind of trigger, same kind of muzzle-flip. It felt like an eternity waiting for my sights to level back out again.”

      Yes, I’ve trained and shot courses of fire many times with a G19 and original M&P, have done so once with a VP9 and a M&P 2.0. I prefer the 320 to all 4 for a variety of reasons. If “muzzle flip” is an issue for you with the very minimal differences in bore height, I’d suggest your fundamentals are in need of serious work.

      I won’t claim the 320 is the “best” pistol because in a lot of ways that’s subjective, but there’s nothing inherently wrong with it.

    • I’ve shot 35,000 rounds through P320s, in 9mm, and 40S&W through 2 guns (most of the rounds fired through one them). Shooting it in USPSA, Steel Challenge, and Bianchi Cup.

      I didn’t have any of the issues you mentioned. The grip modules I used are still perfectly fine. The muzzle flip was maybe a tad worse than the G17 Gen 4, but no worse than the M&P but better than the Walther P99 (the pistol the Caniks copied), and XDM. And dramatically better than Hi Point C9 I shot. No issues with light strikes, even though I load with CCI Primers (come of the hardest in the industry).

      But hey what do I know?

      • Beju

        But I need the lowest bore axis to tame the fearsome recoil of 9mm in a full-sized pistol!

        • Tom_EE

          Then get yourself a Remington R50! LOL

  • Don Ward

    I’m kind of glad the Great Modular Handgun Procurement War is now over for the US military.

    It was a long battle and we lost a lot of good online buddies from the effects of salt hyponatraemia, pouring it all out on comment threads like this.

    I can still hear the cries of my outnumbered platoon of M9 Beretta recon marines that were pinned down in a brutal crossfire between Glocktards and Sigheads.

    To this day, I still wake up screaming, fumbling for the slide mounted safety.

  • Glenn Bellamy

    Yesterday, Steyr sued Sig for patent infringement on the P320 (Patent No. 6,260,301). That will not affect the military contract in any way (Steyr would have to sue the .gov for that). But, Sig certainly has the motivation and means to defend and attack the patent with vigor, even though it will expire in 2019.

    • FOC Ewe

      I love my Steyr S9 and would fly an Austrian Flag in the yard if I could get a 357 Sig conversion along with real mags….

      • Just made my own holster for my L9, love that thing. Would love to be able to shoot .357 sig also somehow

    • I’m not patent lawyer, so my opinion is worth what you paid for it.

      Reading purely off the patents, are some similarities in the two designs, but there is one big difference. The Steyer design the barrel, and the receiver contact the housing/grip module at the same point. Whereas the SIG P250/320 contacts it at the rear.

      I also find it strange that Steyr waited 10 years to enforce their patent, as the P250 has the exact same design in respect to the frame/grip module interface, and was released in 2007.

      • ostiariusalpha

        I think that delay could really hurt their case.

      • I’ve always wondered about this. First time I took my L9A1 home, I disassembled it and was like “holy crap, this is a chassis pistol!” Byt Steyr seemed fine just letting other companies waltz off with the idea… Why?

        • Xerxes036

          I had no idea the L9A1 was a chassis pistol…..

        • redsr

          There are a lot of patent troll lawyers out there who look for patent infringement cases with some chance of success and then pitch the patent holder. Perhaps an outside lawyer contacted Steyr here, Steyr got a new in house attorney w/ patent background, someone in the company decided it was a good way for some free PR, or the sheer volume of guns presumed to be sold due to this US Army contract makes pursuing even an outside chance of a patent case, even if settled out of court, lucrative enough to pursue…

    • Would you happen to have a link or other reference to the lawsuit?

      All I can find is Steyr’s 2015 suit against Beretta over the same patent.

  • Joel

    The experiment begins as the US appears to be the first large scale, military adopter of this relatively new pistol. Good luck.

    • FOC Ewe

      And, this just changes the “flair” on Officer/Sr NCO field uniform.

      Teams won’t be shackled to it anymore than they are the M9.

      • Joe

        Yes, but MP/MA/SP, Security Forces, SRT’s, RTT’s, and TRF’s will.

      • some other joe

        But “teams” will have the opportunity to test them against whatever they’ve bought themselves and decide if special snowflake pistols are worth continued mission funds usage or if what they got for free is good enough. That will be the real outcome of the transition.

  • Audie Bakerson

    Wonder if M17 will be buildable without SIG parts in ~18 years.

  • Rob

    Technically the GAO has until the 5th of June to sustain the Glock protest. Sig is not out of the woods yet.

  • Wayne Moulder

    I, myself, prefer .40 S&W.

    • PaulWVa

      Our local Gander Mtn. is closing and their clearance sale has cleaned out all the brass, bullets and mags. Except 40 S&W…tons left over. You should check into this if you own a .40. Seriously, not a single piece of .38, .357, 9mm, or .44 brass in the place, but I could have bought a couple of thousand rounds of .40 brass.

  • Michael Valera

    Strikers were pioneered by Glock, or popularized by Glock? Methinks its the second one. Very different meanings.

  • USMC03Vet

    These need to come in OD green. Please, Sig!

  • In8ideas

    My new P320 compact .40cal had a catastrophic failure after just 60 rounds.
    It’s my first Sig and chose it over the Glock and M&P. So far Sig support is taking care of it. The guy said he’s never seen this before when I asked if they’re piled up over there waiting to be fixed.

  • None

    Is that a different shade of FDE than the civi versions already out?

    • PaulWVa

      Frame looks the same as mine. My slide is black (blue?). Note that the steel slide is a little different color than the polymer frame.

  • GordonTrenchard

    Waste of money. Of course there are rumors now there problems with the barrels. I heard they only tested them to 12,500 rounds. This might not turn out well.

  • steve2insd

    It’s not like there are enraged muslims still in the southern Philippines that we may end up fighting again . . . oh wait. Make mine .45, tyvm.

    To really be more effective, ditch the treaty mandating ball ammo.

    • No one

      So the military can can use a round, even with both using JHPs, is higher recoiling, gives slower follow up shots, uses a bigger frame, holds less rounds, is heavier, and where you can’t find a single test, or battlefield/trauma surgeon who have seen a gunshot that can tell you the difference between the 2 wound path wise until said bullets are extracted and precisely measured by forensic experts?

      Yeah, THAT will make all the difference in some war with the Philippines!

  • Richard Lutz

    So what are the Navy SEALs going to do with the Glock 19 pistols they adopted in 2015 to replace their SIG MK25 pistols? Don’t see much point to the M17 over the Glock as nobody is every likely to mount a red dot sight on them as they are more trouble than they are worth on a handgun due to the difficulty in finding the dot on a firearm without a buttstock to help locate the dot in front of your eye. Still, I suppose some like the more aggressive mounting rail even if it is more likely to catch on cover and clothing than the one on the Glock. Have they sorted out the misfire issue with the M17 due to its “modular” firing mechanism? I suppose the downside of modularity might be inferior reliability, but as few US soldiers ever fire their handguns in life or death situations I suppose this doesn’t matter much.

    • No one

      SOCOM units doesn’t have to use the same weapons as the standard branches and have much more freedom to do what they want.

      SOCOM will probably just keep their Glocks since there’s really not very many times you’ll actually use your pistol in a modern war anyway.

    • While some XM17 and XM18 will undoubtedly be accepted to replace M9 and M11 in USSOCOM inventory, the “compact” XM18 is still larger than what SOCOM called out for its Low Visibility Concealable Pistol (LVCP) requirement. The LCVP requirement led to the adoption of the Glock 19 and 26. These have since received the designations Mk 27 Mod 0 and Mk 26 Mod 0, respectively.

  • maodeedee

    O.K., it’s striker-fired, but then what is the safety for and what is the trigger like? It looks like it would have a long trigger pull.
