Mark IV 22/45 5.50" 10+1 .22 LR

The Ruger Mark IV 22/45 brings legendary .22 LR accuracy in an elegant package inspired by the classic 1911 aesthetic. Featuring a simple, one‑button takedown, this pistol makes field-stripping and bore-to-muzzle cleaning effortless—no tools required. Its comfortable precision-molded polymer grip frame includes a serrated frontstrap and checkered backstrap, ensuring a secure, comfortable hold whether you're target shooting or competing.

Engineered for long-lasting precision, the Ruger sports a cold hammer-forged barrel with ultra-precise rifling that delivers exceptional shot-to-shot accuracy. The internal cylindrical bolt construction ensures the sights remain permanently aligned with the barrel—providing superior consistency compared to conventional moving-slide systems. A contoured ejection port and prominent bolt ears offer reliable, durable operation even with frequent use.

Complete with features tailored for shooters, the pistol includes an ergonomic bolt stop, checkered 1911-style grip panels, and a drilled and tapped receiver for easy installation of a Weaver- or Picatinny-style rail and optics. Safety and convenience are also prioritized: it offers an ambidextrous manual safety (convertible to left-side only), a push-button magazine release with drop-free magazines, and a magazine disconnect to prevent firing without a magazine. Two 10‑round magazines are included—ready for immediate use.
