Mauser Rimfire 4010102 M20 22 LR 10+1 4.75" Black Steel Threaded Barrel, Black Serrated Slide, Black Aluminum Frame w/Picatinny Rail, Ambidextrous

The Mauser Rimfire M20 22 LR is a precision-engineered semi-automatic rimfire pistol designed for shooters who demand reliability and ergonomic control in a compact platform. Chambered in .22 Long Rifle with a 10+1 capacity, this model delivers low-recoil, low-cost training and recreational shooting without sacrificing the handling characteristics serious operators expect. The 4.75-inch threaded barrel accommodates suppressors and other muzzle devices, while the machined aluminum slide and frame construction keep the pistol light—2.47 lbs—for extended range sessions.

Built around a double/single-action design with an integrated hammer de-cocker and slide-mounted safety, the M20 provides immediate, intuitive operation familiar to anyone trained on duty-grade platforms. Front and rear slide serrations ensure positive grip even in adverse conditions, while the picatinny rail below the barrel enables attachment of lights, lasers, or other targeting accessories. The aluminum frame accepts both standard and high-velocity .22 ammunition, making this an adaptable platform for varied shooting scenarios. Ambidextrous controls allow left- and right-handed operators to manipulate the pistol without repositioning their grip.

This pistol serves shooters engaged in precision rimfire training, indoor range practice, and suppressed duty applications where .22 LR ballistics meet legal and practical requirements. Law enforcement firearms instructors and armed professionals use rimfire pistols like the M20 to conduct high-volume, cost-effective training without the wear on centerfire duty weapons. The threaded barrel, minimal recoil, and full-size ergonomics make it ideal for shooters developing trigger control and sight picture fundamentals before transitioning to higher-power calibers.

The .22 LR cartridge remains the most economical high-volume training round available, and the M20's design—dual-action capability, modern controls, and accessory compatibility—bridges the gap between budget shooting and serious handling practice. The compact 7.9-inch length and aluminum construction position this pistol as a logical training tool for agencies and individuals committed to maintaining skill without depleting ammunition stocks or budgets.
