USA – -(, Ruger & Co., Inc. (NYSE: RGR) is adding three new models to the growing Ruger® Mark IV family of rimfire pistols.

Ruger has long set the standard for reliable, affordable and accurate .22 LR handguns, beginning with the introduction of the Standard Pistol in 1949. In September 2016, Ruger introduced the newest additions to this time-honored family of pistols with three configurations of the Mark IV pistol. Today, Ruger proudly introduces a bronze anodized Mark IV 22/45™ Lite model, as well as Mark IV Hunter and Target models that feature wrap-around target grips.

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. Other new features that are common to the Mark IV family include an ambidextrous manual safety and a redesigned bolt stop for more ergonomic operation.

The Mark IV 22/45 Lite combines a lightweight, precision-molded, polymer grip frame with an aircraft grade aluminum upper receiver. The receiver features an attractive anodized bronze color and pattern-drilled vents for a custom pistol look without the custom price. Chambered in the popular .22 LR, the Mark IV 22/45 Lite is fun to shoot, accurate and reliable. Weighing only 25 oz., the Mark IV 22/45 Lite is the ideal lightweight rimfire pistol.

The Mark IV 22/45 Lite’s CNC-machined aluminum receiver houses a 4.4-inch stainless steel barrel, held in place by a tension nut to ensure accuracy. The Mark IV 22/45 Lite also features adjustable target sights, an installed Picatinny rail for easy mounting of optics and a factory-threaded 1/2″-28 muzzle to accept popular muzzle accessories. The comfortable, precision-molded polymer grip frame incorporates replaceable Hogue® black rubber grip panels that allow shooters to customize the look of the pistol. The Mark IV 22/45 Lite is the perfect outdoor companion and can be used for target shooting, plinking, small game hunting or competitive shooting.

I have a new MK IV Target as well as an S&W Victory. The profiles of these pistols are very similar. The Victory has better sights (good, visible,adjustable sights). I replaced the front iron MK IV sight with a HiVizz fiber optic sight. Easy install and inexpensive. But for me the Victory is the better pistol. More accurate and less money. If I would choose just one it would be the Victory. I also have a MK II Standard and with a 2.5 pound trigge it is a treasure

Rather than complain find yourself a nice used MK III 22/45, mount a Tactical Solutions Pac-Lite barrel and if you don’t like the convoluted takedown procedure buy a Majestic Arms SPEED STRIP kit for Ruger pistols. This will probably cost less than a new MK IV.

Why don’t they offer the stainless version with a 5-1/2″ fluted barrel? They pulled the same trick with the Mkiii. Had to wait until Talo offered it in a 5-1/2″ fluted stainless barrel. And production was so low that you couldn’t find one practically anywhere. Doesn’t make any sense to me. Am I missing something here?
If they do offer such a gun I will immediately order one.


I wish they’d go back to basics…..and come up with a stainless MK IV with a 4 inch barrel. I don’t need long barrels, accessory rails and target style sights. Something like the original 1949 plinker, but with a bull barrel and that great new one-button take-down. THAT I would definitely buy.


Unfortunately, this is considered evil in the socialist democratic republic of Connecticut.. We are not allowed to own a semi-auto firearm that has a threaded barrel.


YES, the lite version is the one with the bronze barrel covering and the black knob at the front is where the threaded part of the barrel is – just unscrew the black knob and the threads are there. All three are very good pistols. I have a Mark II and will not give it up for any amount.

Where’s the threaded barrel?

Joseph Bawden

The lite version is threaded. So it’s at the top I guess.

Unfortunately, I don’t like bronze on my guns. I want a Hunter or a Target with a threaded barrel. Picky, picky!
