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

Engineered for ease of use and shooting versatility, the Ruger Mark IV 22/45 Threaded Barrel model offers a modern twist on a classic rimfire pistol. With its simple one-button takedown, users can field-strip the firearm quickly for chamber-to-muzzle cleaning—no tools necessary. Its precision-molded polymer grip frame, complete with a serrated frontstrap and checkered backstrap, delivers ergonomic comfort during long shooting sessions.

Built for accuracy and adaptability, the pistol features a cold hammer-forged barrel with ultra-precise rifling and a 1/2"-28 threaded muzzle complete with a thread protector—ideal for attaching suppressors or other muzzle devices. A factory-installed Picatinny rail adds optic-ready functionality, while the internal cylindrical bolt construction provides a consistent, sight-aligned firing experience unmatched by traditional slide designs.

From its contoured ejection port and easy-to-grasp bolt ears to its checkered 1911-style grips and ambidextrous manual safety, this model is tailored for both performance and convenience. A push-button magazine release enables smooth reloads, and the magazine disconnect feature ensures added safety by preventing firing when the magazine is removed. Comes complete with two 10-round magazines, ready for use on the range or in competition.
