Smith & Wesson M&P 22 Magnum .22 WMR Pistol
The Smith & Wesson M&P 22 Magnum brings the speed and versatility of the .22 Winchester Magnum Rimfire cartridge to a modern, high-capacity semi-automatic pistol. Built around Smith & Wesson’s innovative TEMPO operating system, the M&P 22 Magnum combines a 30+1 capacity with familiar M&P ergonomics and factory optics capability.
This configuration features a 4.35-inch barrel, optics-ready slide, fiber-optic front sight, flat-face trigger and two 30-round magazines, creating a distinctive rimfire pistol designed for recreational shooting and range use.
Powerful .22 WMR Chambering
The Smith & Wesson M&P 22 Magnum is chambered in .22 WMR, also known as .22 Magnum, providing increased velocity and energy compared with conventional .22 LR ammunition.
The cartridge gives the M&P 22 Magnum a different performance profile from traditional rimfire pistols while retaining relatively mild recoil and enjoyable shooting characteristics.
30+1 Round Capacity
One of the defining characteristics of the M&P 22 Magnum is its substantial 30+1 round capacity.
The pistol uses slim, high-capacity 30-round magazines that provide extended shooting between reloads, making the platform particularly appealing for recreational range sessions.
Two 30-Round Magazines Included
The Smith & Wesson M&P 22 Magnum comes with two 30-round magazines, providing substantial ammunition capacity directly from the factory.
Having two magazines included also gives shooters additional convenience during extended training and recreational shooting sessions.
Gas-Operated TEMPO System
The M&P 22 Magnum uses Smith & Wesson’s innovative TEMPO gas-operated barrel system, developed specifically to support reliable operation with the .22 WMR cartridge.
The system keeps the breech mechanically locked until pressure decreases to an appropriate level, distinguishing the M&P 22 Magnum from conventional blowback-operated rimfire pistols.
4.35-Inch Barrel
The Smith & Wesson M&P 22 Magnum features a 4.35-inch barrel, providing practical dimensions for both range use and recreational shooting.
The barrel works in conjunction with the TEMPO system to create the distinctive operating characteristics of this high-capacity rimfire platform.
Optics-Ready Slide
An optics-ready slide provides factory mounting capability for compatible pistol-mounted red dot sights.
This allows shooters to configure the M&P 22 Magnum with an electronic optic without requiring aftermarket slide machining.
Fiber-Optic Front Sight
The Smith & Wesson M&P 22 Magnum incorporates a fiber-optic front sight designed to provide a bright and easily visible aiming reference.
The high-visibility front sight provides a useful factory sighting solution for shooters who prefer traditional iron sights rather than an electronic optic.
Flat-Face Trigger
A modern flat-face trigger provides consistent trigger-finger placement and complements the performance-oriented design of the pistol.
The trigger design follows the contemporary styling and ergonomics found throughout Smith & Wesson’s current M&P handgun lineup.
Textured M&P Grip
The M&P 22 Magnum incorporates a textured polymer grip designed to provide secure contact with the shooting hand.
The grip geometry provides a familiar interface for shooters accustomed to other M&P pistols while accommodating the distinctive 30-round magazine design.
High-Capacity Rimfire Platform
The Smith & Wesson M&P 22 Magnum combines the increased performance of .22 WMR with 30+1 capacity, factory optics capability and Smith & Wesson’s innovative TEMPO operating system.
For shooters searching for a high-capacity .22 Magnum pistol for recreational shooting and range use, the M&P 22 Magnum provides a modern and feature-rich alternative to traditional rimfire handgun designs.
