Breaking: Ruger MARK IV Rimfire Pistol – The New Announced Product

Ruger Mark IV

The new, unannounced product officially came out from the shadows!

The Ruger Mark IV is here!

Ruger may have answered a lot of prayers with this model. My inclination of a handgun based on their sweepstakes requiring people to be 21 was about as close as I got to guessing this. The Ruger Mark III has always been known to be accurate and reliable, but field stripping it, forget about it. Now you can dis-assemble the Ruger Mark IV with the literal push of a button. If this is not convenience personified, I am not sure what is.

Ruger Mark IV

Push Button Take Down of Ruger Mark IV

To start, Ruger will be introducing this model in 3 different configurations: Mark IV Target Stainless, Mark IV Target Blued and Mark IV Hunter (S/S).

One improvement is an ambidextrous manual safety with a beefed up thumb pad for more positive dexterity. Also, the frame is one solid piece that is CNC machined.

Aesthetically, the gun does not look much different, but these small improvements consumers have been begging to see for years. Ruger expanded upon their new Mark IV and its features:

Ruger is excited to introduce the Ruger Mark IV. While the heavily redesigned Mark IV maintains the same classic outward appearance as the Mark III, it incorporates a significant improvement customers will love – a simple, one-button takedown for quick and easy field stripping. A recessed button in the back of the frame allows the upper receiver to tilt up and off of the grip frame without the use of tools. The bolt simply slides out of the receiver and the barrel can be properly cleaned from chamber to muzzle.

These models should be appearing in brick ‘n mortar stores fairly soon. One thing Ruger is pretty good about is getting new products to market; whereas, a lot of other manufacturers fail to do this in a timely manner.

Right now, the MSRP of these pistols flutters around the $500.00 mark. So your traditional Mark III will still be more economical.

The jury is still out on these in regards to accuracy, functionality, and how tight this new frame-to-upper-receiver fit is. We should see range reviews for this firearm flooding the internet in no time.

    And ruger keeps setting the bar. A high value AR, a high value sniper rifle, now they took the worst part of their .22’s and made it better. You pay for it, tho

    • AK™

      Id love to see a Ruger AR-762 with a 18″ barrel,with a midlength gas system.

  • CS

    Introducing The all new “Ruger Luger”

  • Wetcoaster

    Hot diggity. Will this translate into an update of the 22/45?

    • Some Guy

      A 22/45 With steel or aluminum grip frame construction as an option would be amazing.

      Here’s hoping.

    • Supposedly that’s coming soon.

    • One of the 22/45 “suppressor ready” threaded barrel models, hopefully…

  • Keith Melton

    About time they fixed that major design flaw. The old flawed guns were probably the least properly cleaned guns in America.

    • Buddy_Bizarre

      I think it’s unfair to call it a flaw, it was more likely a design or engineering compromise. Besides, I can usually go about 1000 rds before the gun starts malfunctioning.

      • Some Guy

        Yeah but a few years ago 1000 rounds of .22lr was ~ half a range day.

        This is a solid improvement (in theory) but with .22lr being only about half the cost of 9×19 these days I’m more inclined to simply practice the fundamentals with my actual carry gun (plus: recoil is fun)

    • dltaylor51

      I never strip down any of my auto’s to clean them,just spray them down inside and out with WD-40 let them sit for 10min.and then spray about a half a can of gun blast through them blow them out with air untill dry and spray everything down with rem oil.A little crud inside a gun wont hurt a thing but repeated disassembly and reassembly not so.

    • CountryBoy

      Yet, they just worked and worked.

  • Chandler P

    I wonder if they did away with the magazine disconnect

    • Standard Velocity

      Per American Rifleman the disconnect stays. Hopefully it will be as easy to modify as the Mk III.

      Looks like they did get rid of the loaded chamber indicator though. They listened to 2/3’s of the customer feedback.

      Glad there is still interest in the Mk series. Way more accurate than the other semi auto 22’s I have owned. Put a drop-in VQ sear in and my Mk II would nail golf balls past 50 yards.

  • AC97

    Why didn’t they do this earlier?

    • Tim Pearce

      I’m honestly not trying to throw more garbage on the man’s grave, but Bill Ruger wasn’t exactly known for being in touch with what his customers wanted. This might have been another effect of that.
      Also, it’s not easy to redesign a firearm, keeping the aesthetics, without making a few things unreliable, terrible, or easily broken. It’s entirely possible they’ve been working on this for several years, going back to the drawing board over and over as this or that little detail had to be reworked in order to achieve the customer-desired level of quality and reliability. Imagine if they’d just decided it was good enough and released something with the reliability of the Sig Mosquito.
      Further, we shooters are far too biased toward tradition and keeping to the way things were originally designed. No matter how much people hate the disassembly of the Mark III, it’s possible this new Mark IV will fail, commercially, simply because it’s not the same old school pistol. I can’t say I’m totally innocent on this, as my first thought was, “Oh, finally! Maybe I’ll get one to replace my Beretta,” and then my second was, “Well, I should wait until we know if it’s as good as what it’s replacing.”

      • Anonymoose

        About the only time he ever listened to what the people wanted was when that pre-CASS Cowboy Action shooter-guy asked him to make a Blackhawk in .45 Colt.

  • DaveP.

    Ruger: “Dude, we made it easier to field strip!”
    Me, and a few MILLION other Mark 1, 2, and 3 users: “Gee that took long enough!”
    The original Ruger Standard hit shelves over 65 years ago, and users started complaining about what a pain disassembly was about 30 seconds later. Literally, there’s nations older than the Ruger Mark 1 and 2 complaint file. So hey ,Ruger: Thanks, but next time try to address customer complaints in a timeline that doesn’t involve the word, “Generations”, eh?

  • Spencerhut

    I’m sure I’ll continue to get the Mk 1/2/3 in the store for the next 100 or so years in little baggies after people take them apart and can’t get them back together.
    “Bag ‘o gun”

    • Tim Pearce

      An old coworker of mine was an auto mechanic. He bought a Mark III and decided to find out what people were talking about with how hard it is to reassemble. He finally got it back together with the help of a Youtube video and came out from the back saying, “Never again.”

      • EzGoingKev

        I was a mechanic too. There was a learning curve the first couple of times taking it apart but after that it was no big deal.

        • I agree it isn’t that hard. Spend a couple of hours taking it apart and putting it back together while fitting after market trigger parts will result in your being an expert on Ruger Mk 1-3 assembly.

      • Spencerhut

        Heard it a million times. When a popular aftermarket add on for your gun is a kit to make it easier to take it apart, you might have a Ruger Mk 1/2/3.

      • Swarf

        I have a friend who got a free gun that way; one of his (Well off) friends took apart his Ruger, got frustrated trying to put back together and just put all the parts in a bag for years until the topic came up in conversation, at which point, he just handed my (mechanically inclined) buddy the bag).

        He then promptly figured out how to put it back together. Free gun.

        Meanwhile, the other guy just went out and bought himself a different toy. I don’t know what. Airsoft, I hope, but probably not, since that’s the same rich guy who just HAD to have a 10mm Glock as his first hand gun and a fancy pants AR as his first rifle. Money.

        • CountryBoy

          Wanna give him my info when he tries to field-strip his Glock or AR? That rear pin on the AR can be a booger sometimes! 😉

    • The Ruger MkII Permanent Gunsmith Employment Device.

    • mazkact

      A friend of mine who is retired now owned a gun shop for many years. Whenever someone would ask about working for him the test He gave was to dissemble and reassemble a MK series pistol without a manual. This weeded out the self proclaimed “gunsmiths”.

    • T100C1970

      About 4 years ago, it took me and friend (both former army officers
      and veterans of 50+ years of shooting) over two hours to reassemble my
      Mark III. The main obstacle was literally having to beat the bolt
      stop pin back into place. The Mark III has functioned flawlessly ever
      since and has never been taken down again!

    • silentfor56years

      When my son-in-law went to Afghanistan I used his MarII in a Bulls eye League. Thank God for YouTube or I never would have gotten it back together after cleaning it.

    • Derek Johnson

      The fact that these accounts are true really worries me regarding the intelligence of the modern American. It’s really not that hard. The tight fit of my MKIII is FAR worse than the actual assembly process, even when the magazine disconnect was still installed.

  • Dickie

    Basically their answer to the new S&W 22Victory.

    • Jeff Smith

      My thoughts exactly. I bought my MKIII 22/45 fight before the victory came out and I almost wish I had waited. I love the gun, but disassembly is a nightmare.

    • Anonymoose

      Except the new Ruger will still cost more, so the Victory will still be victorious!

      • The Victory will always look like a manufacturing error next to the clean and elegant form of the MkIV, though.

  • David B

    “allows the upper receiver to tilt up and off of the grip frame without the use of tools. The bolt simply slides out of the receiver and the barrel can be properly cleaned from chamber to muzzle.”
    Hey, now they field strip like an AR.

  • Cymond

    My gut reaction was “oh, another generation of the Mark series. OK, whatever” until I read the details. This will throw a monkey wrench into Volquartsen’s operations, but it’s a huge step forward overall. I guess the S&W Victory lit a fire under their chair. I like the CNC machined lower, too. Looking at the Victory closely on YouTube, I was a little put off by the stamped sheet your and cast(?) bolt, compared to the machines Ruger parts.

    If I were planning to buy something in this class, I would probably pick the Mark 4. However, I don’t feel the need to run trade my Mark 3 at all.

  • Drew Coleman

    Am I the only one who doesn’t find field stripping the Mk III to be difficult? I don’t find it any harder than my 1911’s. My one major gripe with mine is the magazine disconnect, which I removed when I installed a VQ trigger, hammer, and sear.

    • derpmaster

      If you’ve never done it before and have no prior knowledge, it’s hard, particularly to reassemble. It’s also hard if you get some kind of major jam. I’ve had to hammer these things apart before for people who aren’t familiar with the design. This is probably why I’m a Buckmark fanboy instead of Ruger – the Buckmark requires hex keys (also the bolts work themselves loose over time) but at least it’s intuitive.

      • Drew Coleman

        I find it to be perfectly intuitive if you look at each piece and how it interacts with everything else – once you understand that, it’s much easier.

        • Hinermad

          I think it’s how the parts inside where you can’t see them interact is what throws people off. I had a Mk II 30 years ago and after a half hour of fiddling figured out how to put it back together. Then I sold it, and got another one two years ago. I had completely forgotten how to put it back together. Then I figured out how to hold it so the (out of sight) hammer was in the right position, and it snapped right back together.

          • Uncle Festet

            Exactly. Although I pulled it off, it took an inordinate amount of time to get everything reassembled and I don’t think I could have done it without the Internet & YouTube. I sold mine and bought a Victory.

    • Uncle Festet

      Yes you are. As this redesign illustrates, the old design was unnecessarily difficult to take apart.

      • T100C1970

        I found it trivially easy to take APART. Putting it back together is the problem.

    • It certainly gets easier and faster the more often you do it, but it never stops being a pain in the ejection port.

      • Longhaired Redneck

        “…a pain in the injection port”.

        Good stuff!

  • Swarf

    Well, congratulations to those who are excited for it. It looks like a nice pistol.

    I was hoping for something a little more interesting than another gun in a caliber that is twice as expensive as it was a few years ago.

  • I’ve never found the Ruger Mk. 3 to be especially difficult to take down. However I have found the process to be irritating, pointy, and counterintuitive.

    • Nicholas C

      Takedown is not the problem Reassembly is a bit of an annoyance.

  • Nicholas C

    All I want to know is, will there be a threaded barrel version?

  • Anonymoose

    Yesterday I was angry about this, as they dropped their PCCs and introduced this thing. I’ve accepted it now, I guess, but they better have some integrally suppressed models from the factory, and allow the barrels to be changed without going to an FFL every time to get a new upper.

    • DaveP.

      Looking at the picture at the top of the article, it looks like the serial number is still on the barrel/receiver group- which means that that’s the actual gun (as per the ATF), so no barrel swaps.

      • Holdfast_II

        Lots of guns have a copy of the serial number on another part, like the barrel. I wouldn’t take that as dispositive.

        • DaveP.

          True, but if you go to Ruger’s website they show both sides plus the frontstrap and backstrap of the grip and there’s only the one set of numbers. Sorry, but there it is.

  • gunsandrockets

    Now if Ruger would just offer the baby model.

  • Jeff Smith

    It kind of annoys me that manufacturers no longer preview a large amount of their products until a few weeks before they are released. EX – had I known that the S&W Victory was being released a week after I bought my Ruger MKIII 22/45, I would have probably waited. It would be nice to know something is coming out, say, a few months ahead of time, even if the only thing being announced is some type of concept (i.e. – “we plan on releasing a full size dedicated .22lr autoloading handgun that improves upon out MK series of pistols and simplifies the disassembly process next quarter.”).

    Maybe that’s optimistic, but I can’t tell you how many times I’ve spent $500ish on a firearm and immediately wished I had waited after seeing Company X is releasing something similar.

    • kipy

      Well if you’re a Kel Tec fan you get to wait for years before getting the option of buying one of their new products.

    • Would you rather have that problem, or still be waiting for the MDR you pre-ordered two years ago? Given the example of how apocalyptically bad Remington’s R-51 has turned out– thanks to a Microsoftian product release plan that effectively makes the end user the beta tester– I would much rather a manufacturer take the time to get a design right first, then release it, rather than make so many promises in advance that they’re pressured to dump an unfinished design on the market.

  • Reid

    Two thoughts:
    1. The Ruger Mks have always been some good-looking pistols. I wish that more handguns with a similar aesthetic were available in more calibers (with beefed-up internals, obviously).
    2. I was really hoping the new product announcement was a factory SBR Mini-14/30 in some kind of decent-looking stock that wasn’t ultra heavy.

  • sb

    long live High Standard……

  • Hoplopfheil

    Cough cough Smith 22a-1 cough

    Excuse me. Something in my throat.

  • Schnee

    The original is an IQ test and a sidearm all in one. I propose that anyone who can disassemble and reassemble a MK 1/2/3 in less than one minute should be allowed to own any firearm they want, including belt-fed machine guns. If you can’t then you can have a can of mace or a wood gun.

    • CountryBoy

      Is that the new Block 17?

  • Christian Hedegaard-Schou

    I think the real question is, does it take MKIII mags, or does it take new MKIV mags?

    • kipy

      22 Plinkster confirmed mklll mags work in it

  • Bigbigpoopi

    Bet it still has the mag safety

  • As a MkII owner who’s spent almost as much time fighting that %#$& mainspring as actually shooting the dadgum thing, I really think this announcement should have come with musical accompaniment in the form of the Hallelujah Chorus combined with the 1812 Overture.

  • Edeco

    Don’t like the appearance. Saccharine and blocky. Only a bit worst than the Mk III but a step in the wrong direction.

    If it were something paradigm shifting I wouldn’t mind. I’m part of the Glocks-are-pretty camp even tho they fart in the face of 1911 and revolver type aesthetics*. But come on, 2 lbs of metal, $400-ish pricetag, only got to touch off 22’s… can you not do better?

    *by your leave, any ladies who read that.

    • uisconfruzed

      I’m hitting a 10″ plate 9 out of 10 rounds standing, unsupported at 75 yards with mine. I’m hitting a golf ball on average of 1 out of 10 rounds at 100 yards.
      I’s my favorite gun to shoot. See the pic above.

      • Edeco

        Impressive. Your skill deserves better from Ruger. It’s like if Mario Andretti had to drive a Chevy Malibu, or a Ferrari chassis with a Malibu skin on top.

        • uisconfruzed

          It’s stupid impressive & makes me look great. For some reason I shoot a pistol better at 50 & 75 yards better than a rifle freestanding.
          I’ll tell someone that has never shot a pistol they’ll hit the 50yrd plate by the second round & they almost always do.

  • derfelcadarn

    I own several of the earlier Mark series guns and they are fine, if Ruger really wished to offer a badder version then scaling it up to 22mag. would be the ticket. Thjis is just an also ran.

  • Dr. Longfellow Buchenrad

    The front hinged takedown system used by the AR, FAL, and now Ruger Mk4 is something I really like.

  • Jim_Macklin

    The only difficult part about reassembling the MK I II II is you have to tilt the muzzle uo so the hammer link swings free so you can capture it on the mainspring plunger. Most problems have the hammer strut catching on the frame cross pin. The MS housing snaps closed without any compression.
    Simple, I’ve fixed many improperly assembled guns in the past 60 years or so. No tools required if you use the magazine tube to release the latch.
    I do like the ambi safety

  • GrumpyCat

    It appears that there is NOT a loaded chamber indicator. Good. That’s a stupid feature to placate anti-gun states that made the gun look bad and provided no value to the user.

  • RickfromPaso

    Doggone, another gun we won’t be able to get until I leave Kalifornia!

  • nagurski

    Ever since my rent got cheaper, I’ve been strongly considering a new handgun purchase. Honestly, my top two choices were the Ruger LCR and the Ruger Charger. Now I have to add another choice onto the list though.

  • mazkact

    I’ve never understood the frustration over MK I,II and III reassembly. Read the manual do it as described…………..Bobs your uncle. OK. removing the upper from the lower can at times be aggravating but this is seldom if ever necessary. The most boringly accurate semi handgun I own is a MK II Government Target. My MK III 22/45 target model is nice after removing the LCI and the trigger robbing and irritating mag/trigger disconnect. I had hoped the MK IV would come from the factory minus any mag/trigger disconnect but according to their website it has it. The mag “safety” is there so they can sell these guns in 2 A restrictive states but those states are getting so hard to sell any kind of gun in I say why bother. At least Ruger and everyone else should make magazine “safeties” an option not standard. The milled frame on the MK IV is nice but it adds unnecessary cost in manufacturing. I’ll bet the MK IV 22/45 will be rolled out within a couple of months.

  • Devil_Doc

    Why hasn’t someone made a .17 HMR/Mach2 semi auto pistol?

    • ostiariusalpha

      The other rimfires have a larger market share, so naturally, they get all the new firearm designs. If the market gets overcrowded and there is perceived demand for .17 rimfire chamberings, then manufacturers will invest in guns for them. Savage is ahead of the game, making a killing with their A17 (despite that, like the 10/22, it needs considerable aftermarket improvements to reach its full potential). If you harp on it in as many forums as you can, and convince others to do the same, you’ll get manufacturers’ attention. Petition them directly and persistently, and you will get results. Or you could just make a few one-off comments here and there, and live with your disappointment.

  • T100C1970

    I’m still suspicious of this terminology (one button takedown) until I actually see it done. My Mark III is as easy to take DOWN as one of my 1911s — It is putting the damn thing back together where the trouble starts.

  • Just say’n

    My Mark III 22/45 is one of my most favorite guns. I shoot it a lot. Cleaned it once. Never again. It shoots great clean or dirty anyway.

  • HR Pufnstuf

    As the owner of a 1949 MK1, I was disappointed when I got a MK III and a 22/45 with all the “politically correct” features. Loaded chamber indicator. magazine disconnect. Just try to break those things down and put them back together. Magazine in! Pull the trigger. Magazine out! Flip this. Pull that. Take a mallet and BEAT the barrel off of the gun (the 22/45 won’t come apart without great force), and then start all over again to reassemble it. I think that magazine has to be inserted and pulled out 6 times to take that thing down and put it back. And what about a threaded barrel? I don’t see any mention of that. Going to have to set my silencer aside now?

  • dltaylor51

    Taking apart to old Ruger 22 autos is fairly easy but putting them back together again is a nightmare.

  • uisconfruzed

    I love my MII & MKII, both with Voquartzen MKII firing groups. Diss & re-assembling them isn’t bad after you’ve done it a few times.
    I would *LOVE*, to see one that takes a 30 round mag! https://uploads.disquscdn.com/images/cf8e5d579a1a8b4c59dfd88f69ebe0180258499882ba2a01007cdb3eaebfb151.jpg

  • Boss

    I bought a MKII stainless bull barrel in1982 or 83. I used it to compete in silhouette, shot thousands and thousand of rounds thru it and it is still as accurate as when I was winning matches in the 80’s and 90’s. 2008 I called Ruger to tell them It would no longer feed the rounds to battery.

    They sent me a new main spring and guide rod. It worked fine after I got the freakin thing back together. It seemed to crankier with age, I had taken it apart and reassembled it for years with little difficulty and then it got obnoxious.

    I love it anyway, I was able to compete and win against Thompson Contenders with scopes.They separated me to a new iron sight class.

    I will get a MK4.

  • ed nusso

    Sure glad they did this mod.,I really liked the pistolsbrownings but i sold mine and bought Buckmarks and old high standards because they were such a pain in the a__ to take apart and clean, I wish they would come out with a bolt/slide like the Brownings

  • Mitchell Collett

    try the new MK1V……take apart and put back together in 5 seconds or less……yes ,5 seconds or less…..

    • Mitchell Collett

      and yes, Ruger did listen………..
