Ruger Mark IV Tactical 22/45 .22 LR Pistol 4.4" Threaded Barrel - 1/2x28

Combining classic 1911 ergonomics with modern rimfire technology, the Ruger Mark IV™ 22/45™ Tactical .22 LR Pistol is built for shooters who demand accuracy, modularity, and effortless maintenance. Purpose-built as an ideal suppressor host, cross-training handgun, or range plinker, the 22/45 Tactical features a lightweight polymer grip frame molded to replicate the feel and grip angle of a traditional 1911 pistol. The standout feature of the Mark IV platform is its simple one-button takedown system, allowing quick, tool-free field stripping for hassle-free chamber-to-muzzle cleaning.

At the center of this tactical rimfire pistol is a 4.40-inch cold hammer-forged alloy steel barrel, factory threaded in 1/2"-28 TPI to accept popular rimfire suppressors and compensators. Its internal cylindrical bolt design ensures continuous sight-to-barrel alignment for superior precision, supported by a fixed front sight and a fully adjustable target rear sight. Outfitted with a drilled and tapped receiver for optic mounting, an ambidextrous manual safety, push-button drop-free magazine release, and a magazine disconnect safety, the Mark IV 22/45 Tactical ships complete with two 10-round magazines.
