Smith & Wesson M&P 22 MAGNUM | 4.35in | 10rd | 14090

The Smith & Wesson M&P 22 Magnum is a full-size, optic-ready semi-automatic pistol chambered in .22 Winchester Magnum (.22 WMR). It features a 4.35 inch Tempo barrel system with a stainless-steel slide finished in Black Armornite and a black polymer frame with a Picatinny-style rail. For an out-of-the-box micro red-dot that pairs well and stays under $1,000, consider a compact model such as the Holosun 507K or similar Shield/RMSc footprint optic.

Common real-world uses include range-oriented target shooting and small-game/varmint field work where rimfire magnum performance and a lightweight platform are desirable.
