Nashville, TN - Sturm, Ruger & Co., Inc. (NYSE: RGR) is excited to announce the latest development in the Mark Series line of pistols – the Ruger Mark IV. Ruger has long set the standard for reliable, affordable and accurate.22 LR handguns, beginning with the introduction of the Standard Pistol in 1949. Since then, the Standard Pistol has undergone a series of enhancements with the development of the Mark I, Mark II and then the Mark III in 2005. 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. “We are thrilled to be introducing what we consider to be a monumental improvement to this iconic pistol that has been with Ruger from the start,” said Ruger President and COO Chris Killoy. “This one-button takedown alleviates the headache that our Mark III owners are all too familiar with and we anticipate the Mark IV pistols being some of the cleanest rimfires at the range,” Killoy concluded. Other significant improvements include a one-piece grip frame that is precision CNC-machined from a solid piece of stainless steel or aluminum; an ambidextrous manual safety and a redesigned bolt stop for more ergonomic operation. The magazine drops free on release for faster reloads and a redesigned magazine disconnect safety prevents discharge when the magazine has been removed. Internal improvements include changes to the hammer, sear, bolt and firing pin for smoother, more reliable feeding. Specific features vary by model, but the legendary, one-piece barreled receiver and internal cylindrical bolt construction remain the same.

The robust design ensures permanent sight-to-barrel alignment and higher accuracy potential than conventional moving-slide designs. The Mark IV is compatible with a variety of Mark III aftermarket accessories including sights, scope bases and magazines. The American-made Mark IV pistol ships with two 10-round magazines.

I throw everything at the SR22.

Thunderbolts, white box Winchester whatever. I have even mixed the ammo in the mags to show others it can handle it. I know many people with them and they run where the Mark series fail as well as Walther and cheapies like Jennings etc don’t feed the cheap stuff at all. The light rail underneath is perfect for the handicapped wife to use as defense as well. I know someone will get all bent over that but its what she is capable of so beat that drum elsewhere. I’m sure this will fit a niche like some say with competitors (after modifying it) and those stuck on old but want the new twists. This gun will appeal to the typically non-mechanical person who doesn’t want to learn how to do anything.

People complain about the difficulty of taking both the Ruger Marks apart as well as the 1911. With a little concentration and practice, it is not hard. The same people who don’t want to learn how to take a gun apart are the same people who drive automatic transmission cars because it’s hard to learn how to drive a manual.

I wouldn’t allow my daughters to get a drivers permit until they could drive a manual and one shouldn’t be allowed to shoot a firearm until they learn how to take them apart and put them back together. I like my Mark III, my 1911 and manual transmissions. My Mark II has been taken apart and reassembled countless times. Its not difficult once you understand how to do it. I understand if you’re lazy or below average intelligence you would want this new Mark IV over the older ones due to the takedown.


But seriously, the Mark II is easier to take down and reassemble WITHOUT BREAKING SOMETHING than an SR-22 with its goofy plastic tabs and whatnot. It was my very first firearm and I will never give it up. And yes, I own a manual transmission too. It’s not about “easy” or “hard”. It’s about necessary or not. Learning how to drive a manual gives you certain benefits.

Not everyone actually cares about benefits, and not all cars are designed to make good use of them, so not learning to drive manual is not necessarily “lazy” – if you don’t need it, it’s just smart use of your time. The mechanical and disassembly complexity of Mark III, though, is completely unnecessary, as evidenced by other designs (and, indeed, Mark IV) being much simple without compromising anything. So there’s absolutely no downside here.

I bought the Victory (couldn’t pass it up for $300 at a local store) because I have a pro series 686+ Smith revolver that has been flawless (and much better made than the Ruger sp101 I own). I liked the Ruger mark 4 also but the model I would have bought was priced more than $200 above what I paid for the Victory. The takedown screw issue is no big deal and its stock sights are wonderful. The Victory or Mark 4 are both great guns. If I see a good deal I may purchase a Ruger also.

Safety Continued

Ruger’s customer service can’t be beat. “The totally awesome Ruger Mark I, II and III.22 LR pistols were a nightmare to clean.” Nightmare? That’s a pretty strong word. As I’ve been told many, MANY times, I am not a genius, and yet I figured out how to reassemble the MK-I/II pistols all by myself, many years ago. Since then, many others have also done so, and many more have facilitated easy reassembly by others by making videos and posting them online. For any person who takes the time and makes an effort to understand the pistol’s basic mechanical properties, it REALLY is not that difficult.

In fact, over the last decade or so, I’ve used the reassembly of a Ruger MK-? Pistol as one of my quick internal basic judgement tests for the relative skill, perseverance and talent of other newly-met “gun people”, in person and online. Seriously, folks, if you can’t handle this basic reassembly task (tear-down and actual cleaning were never the real problems, based on my observations of others) after some video or brief personal instruction, maybe you should be shooting something simpler, like a longbow. Having said that, I’m still happy to see the MK-IV and it’s improvements, as long as it still shoots well with common modern.22 ammo, whenever this mythical ammo can be found at a reasonable price. Even the mechanically disinclined deserve a chance to enjoy shooting, and the MK-IV should help introduce some new shooters to the fold.

The MkI, MkII and MkIII were hardly difficult to disassemble and clean. They’re simpler than a great many other guns to detail strip and clean. The Colt Woodsman is more complicated to detail strip, and the S&W Model 41 is a real challenge. The Beretta M9/Model 92/Model 96 is a spring&detent bomb, waiting to go off as you strip the slide. By comparison, the MkI/II/III is pud-easy.

It doesn’t launch parts across the room, there’s no little detents and pins that get launched into orbit if you’re not ready to contain them. Want a real challenge in a handgun? Take apart a Colt E/I/etc double-action revolver with timing problems. Oh, there’s very few parts, but the relationship of those few parts, especially the rebound lever to the hand, bolt, etc – is very complicated.

Want to appreciate the MkI/II/III? Then detail strip a Beretta M92. After you do that, you’ll appreciate the MkI/II/III as paragons of simplicity. Mark 1V is just a new type mark 111 with all it’s issues. Yes I made the mistake of purchasing the new hunter model. As of tonight it is on it’s way back to Ruger for the second time.

After 150 rounds it started to come apart.Loose ejector, front pin walked out. Will not shoot any brand of HP ammo without jamming.

50-50 with round nose. Ruger sent it back with residue loctite in the receiver and a new rivit in the ejector that looks like it was put in with a ball peen hammer. Took it to the range today. Still jams with any brand ammo I tried.

Again call RUGER and again it’s on it’s way back. The one button take down is nothing but a gimmick. I’ll sell it when it gets back of course with the paper work from ruger that says everything is just fine. I’ll continue to enjoy my mark 1’s and 2′ and enjoy getting my hands alittle dirty cleaning them. Oh yea my granddaughters can bread down and assem my marks.
