The M & P22 Compact rimfire handgun is similar to the original M & P22, but about 15% smaller. Designed as a dedicated .22 LR, the M & P22 pistol combines the look, feel, and familiar operating features of the trusted M & P series of centerfire pistols. The M & P22 is ideally suited for training or simple shooting enjoyment with the popular and inexpensive .22 LR cartridge. This model features an aluminum alloy slide and a rear white 2-Dot sight that’s screw-adjustable for windage and elevation. The threaded barrel accepts a 3/8″x24 to 1/2″x28 adapter(not included) for suppressor use. Captured recoil guide rod and spring for easier assembly/disassembly. Ambidextrous manual safety. Reversible magazine release. Picatinny accessory rail.
