Mauser Rimfire 4010101 .22 LR 4" 11-Round Pistol

The Mauser Rimfire M20 22 LR is a compact semi-automatic pistol engineered for precision target work, small-game hunting, and recreational shooting where .22 Long Rifle ballistics and low recoil are advantageous. Featuring a machined aluminum slide with front and rear serrations, ambidextrous controls, and a 10+1 round capacity, this 4-inch barreled platform delivers the balance of ergonomics and functional accuracy expected from modern rimfire defensive and training applications.

The M20's machined aluminum construction accommodates both standard velocity and high-velocity .22 ammunition, a critical advantage for shooters who demand versatility across different load specifications. The double/single-action trigger mechanism with hammer de-cocker and slide-mounted safety provides both operational flexibility and consistent trigger control across target and duty scenarios. The Picatinny rail integrated into the aluminum frame permits mounting of tactical lights, lasers, and optics—standard in modern platform design. Ambidextrous controls ensure accessibility for left and right-handed operators, while the black serrated slide and molded grip deliver a professional tactical appearance with functional purchase during extended shooting sessions. At 2.44 lbs, the platform remains manageable for sustained training without fatigue.

This configuration serves competitive rimfire shooters, small-caliber training platforms, and operators seeking a low-recoil, low-noise option for close-quarters and indoor facility work. The .22 LR chambering delivers adequate terminal performance for small game and pest control while generating minimal sound signature and ammunition cost. Compact dimensions and the rail-ready platform make the M20 suitable for backup configurations, training rotations, and precision marksmanship development across law enforcement and civilian operator communities.
