Mark IV 22/45 Tactical 4.40" 10+1 .22 LR

Designed for shooters who demand tactical performance and flexibility, the Ruger Mark IV 22/45 Tactical brings refined accuracy and ease-of-use in a suppressor-ready configuration. The one-button takedown feature makes disassembly and thorough cleaning fast and hassle-free. A precision-molded polymer grip frame with serrated frontstrap and checkered backstrap offers a stable, ergonomic hold—ideal for both extended range sessions and competition environments.

Built around a cold hammer-forged barrel with a 1/2"-28 threaded muzzle, this model is ready to accept a variety of popular suppressors and muzzle accessories. Its internal cylindrical bolt construction ensures sight-to-barrel alignment remains consistent, enhancing accuracy beyond traditional moving-slide pistols. A contoured ejection port and tactile bolt ears contribute to reliable cycling and comfortable operation.

Tailored for tactical versatility, this model includes a drilled and tapped receiver for Weaver- or Picatinny-style rails, supporting easy optics integration. The checkered 1911-style grips, ambidextrous safety (convertible to left-side only), and push-button magazine release further support rapid, intuitive handling. The magazine disconnect and included pair of 10-round magazines round out a feature-rich platform built for serious rimfire shooters.
