Ruger Mark IV 22/45 .22 LR 5.5" Blued 10+1 40107

Ruger Mark IV 22/45

The Ruger Mark IV 22/45 is a single action rimfire pistol chambered in .22 LR with a 5.50 inch blued bull barrel and 10+1 capacity. A polymer grip frame with checkered 1911 style panels sits under an alloy steel receiver that is drilled and tapped for a Weaver or Picatinny rail. Fixed front and adjustable rear sights, an ambidextrous manual safety, and two 10-round magazines complete this target oriented 22/45.

One button takedown lets the barrel and receiver tilt off the grip frame without tools for chamber to muzzle cleaning. Internal cylindrical bolt construction keeps the sights aligned with the barrel, and a cold hammer forged barrel with a 1:16 RH twist supports consistent groups. A contoured ejection port, bolt ears, drop free magazines, and a left side push button magazine release keep range use simple. A magazine disconnect prevents firing when the magazine is removed.

At 9.75 inches overall, 1.22 inches wide, 5.50 inches tall, and 34.4 ounces, the 22/45 is built for target work, competition, and plinking. The 1911 style grip angle feels familiar to shooters who already run a 1911. It suits anyone who wants a classic Ruger .22 pistol with easy takedown, adjustable sights, and two magazines in the box.
