The Smith & Wesson M&P22 is a semi-automatic pistol chambered in .22 Long Rifle, designed with a hammer-fired, blowback-operated mechanism, distinct from the striker-fired, recoil-operated centerfire M&P variants. The M&P22 features a single dot front sight and an adjustable notch rear sight for windage and elevation, along with a Picatinny rail for mounting accessories. In 2013, the M&P22 Compact was introduced as a scaled-down version, perfect for concealed carry, target shooting, and training. The Compact variant retains the ergonomic design and safety features of its full-sized counterpart, including an ambidextrous manual safety, reversible magazine release, and a magazine safety that prevents firing without the magazine inserted. Additional features of the M&P22 Compact include a 3.6" carbon steel barrel for enhanced accuracy, a polymer frame with an aluminum slide to keep the weight low, and a captured recoil guide rod and spring for easier assembly and disassembly. The pistol is equipped with a 3-dot sight system, with the rear sight being fully adjustable. The compact design, combined with these features, makes the M&P22 Compact a reliable, user-friendly option for shooters seeking a versatile and durable .22 LR pistol for various applications.
