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

The Ruger Mark IV™ 22/45™ Tactical is a precision-built rimfire pistol designed for shooters who demand performance, versatility, and ease of maintenance. Chambered in .22 LR, this full-featured tactical platform blends the classic 1911-style grip with modern enhancements, making it ideal for training, plinking, or suppressed shooting.

Its standout feature is the simple one-button takedown, allowing quick and tool-free field stripping for thorough cleaning from chamber to muzzle. The cold hammer-forged, threaded barrel (1/2"-28 TPI) ensures exceptional accuracy and compatibility with popular muzzle devices, while the internal cylindrical bolt construction maintains perfect sight-to-barrel alignment for superior precision.

The polymer grip frame is molded for comfort and control, with checkered 1911-style panels, a serrated frontstrap, and an adjustable rear sight paired with a fixed front sight. The receiver is drilled and tapped for easy optic mounting, and the ambidextrous safety can be converted to left-side only for personalized control.
