The M&P 22X uses a single-action-only, internal-hammer system with a flat-faced trigger and integrated safety blade for a consistent pull. Controls include ambidextrous slide stop levers and a left-side magazine release. The warning on the frame indicates it is capable of firing with the magazine removed, confirming the absence of a magazine disconnect.
Construction is centered around a polymer frame and a black-finished aluminum slide, keeping weight to about 16 oz unloaded. Overall length is approximately 7.25 in, and capacity is 20+1 rounds of .22 LR, supported by double-stack magazines.
Sight configuration is straightforward and fast: a green fiber-optic front sight paired with a black rear notch. A dust-cover Picatinny accessory rail provides mounting space for compatible lights or other rail-mounted accessories.
Markings are clear and model-specific: the slide is marked "M&P 22X" and the chamber is marked "22LR," with a Maryville, TN U.S.A. rollmark. Launched on July 22, 2025, the pistol’s 20-round magazines are also used by the S&W FPC 22LR carbine, offering convenient cross-compatibility.
