Also known as: M&P 22X, MP 22X
Overview
The Smith & Wesson M&P 22X is a full-size, .22 LR semi-automatic pistol introduced in 2025 as a dedicated rimfire training analog to the M&P 9mm platform. Chambered in .22 Long Rifle with a 20+1 round capacity, the M&P 22X features a 4.1-inch threaded stainless steel barrel (1/2x28 threads) with a 1:15-inch twist rate, an overall length of 7.25 inches, height of 5.75 inches, width of 1.13 inches, and an unloaded weight of approximately 16.3 ounces (463g). The pistol operates on a simple blowback action with an internal hammer-fired mechanism, delivering a crisp, lightweight trigger pull. The slim polymer frame is paired with an optics-ready slide pre-cut for micro red dot sights. Standard sights include a Hi-Viz LiteWave H3 fiber-optic front sight with swappable color inserts (red, green, white) and a blacked-out serrated rear notch. The M&P 22X features a manual thumb safety, magazine disconnect, flat-face trigger, reversible magazine release, and a Picatinny accessory rail. The pistol's 20-round magazines are cross-compatible with the M&P FPC 22LR carbine, providing a shared magazine ecosystem between the pistol and rifle platforms.

Notes
The M&P 22X was launched alongside the M&P FPC 22LR pistol caliber carbine at SHOT Show 2025, signaling Smith & Wesson's renewed commitment to the rimfire market. The 22X is designed to closely replicate the ergonomics, controls, and manual of arms of the centerfire M&P platform, making it an ideal training pistol for M&P owners who want to practice fundamentals at reduced cost. The 20-round magazine capacity and magazine compatibility with the FPC 22LR carbine create a compelling rimfire ecosystem. Despite its .22 LR chambering, the pistol features premium touches like the Hi-Viz fiber-optic sight system and optics-ready slide that were previously reserved for centerfire models.
Background
The M&P 22X represents Smith & Wesson's answer to the growing demand for rimfire training pistols that faithfully replicate their centerfire counterparts. By combining the familiar M&P ergonomics with a 20-round .22 LR magazine and cross-compatibility with the FPC carbine, the 22X carved out a unique niche as both an affordable training tool and a recreational plinker.
