The Ruger Mark IV 22/45 combines the ergonomics of a 1911-style grip angle with the proven Mark series action, making it an outstanding platform for optic-equipped rimfire training and competition. The cold hammer-forged bull barrel at 4.40" offers exceptional accuracy and a 1/2x28 threaded muzzle for suppressor or compensator attachment, while the factory-installed Picatinny rail enables direct mounting of red dot sights. Ruger one-button takedown allows disassembly without tools in seconds, and the ambidextrous manual safety converts to left-side only with the included washer. Two 10-round magazines and adjustable sights are included.
