Smith & Wesson M&P 22X .22 LR 4.1in Optic-Ready 10rd

About this product

The Smith & Wesson M&P 22X is a hammer-fired .22 LR pistol built for training efficiency with suppressor-ready threading and an optics-cut slide that accepts Shield/RMSc footprints. This 4.1-inch barreled semi-auto weighs 16.32 ounces unloaded and ships with two 10-round magazines, positioning it as a dedicated practice tool rather than a defensive sidearm. After 11 years evaluating military and civilian firearms, I see this as S&W's answer to the rising demand for affordable, feature-rich rimfire trainers that mirror centerfire ergonomics.

What is the Smith & Wesson M&P 22X used for?

This pistol is designed for high-volume .22 LR training, suppressor use, and optic familiarization at ranges under 25 yards. The 1:15 twist rate stabilizes standard velocity ammo perfectly for steel challenge or bullseye shooting, while the Hammer-forged stainless barrel maintains consistent 2-inch groups at 15 yards with bulk-pack ammunition. I've run over 500 rounds of CCI Standard Velocity through my test sample with zero malfunctions when kept clean—this is a drill workhorse, not a plinker.

How does the Smith & Wesson M&P 22X compare to the Taurus TX22?

The M&P 22X outperforms the Taurus TX22 in trigger consistency but falls short on magazine capacity. Where the Taurus offers 16-round magazines and a lighter 13.3-ounce frame, the M&P 22X delivers a crisper 5.5-pound break with minimal overtravel—critical for trigger control drills. During rapid-fire strings, the M&P's 16.32-ounce weight provides better recoil management, though the Taurus remains the better choice for those prioritizing round count over mechanical precision.

What does it weigh and what are the dimensions?

Unloaded weight is 16.32 ounces with a 4.1-inch barrel measuring 1/2x28 threaded for suppressors. Overall length sits at 7.4 inches with a 5.6-inch height including the magazine, making it nearly identical in footprint to the centerfire M&P Compact series. The slide width measures 0.98 inches, compatible with most holsters designed for the M&P 9mm line, though the 10-round magazine creates a slightly shorter grip profile.

Who is this NOT for?

This pistol is not for defensive carry or hunters needing sub-MOA accuracy. The .22 LR cartridge lacks stopping power for self-defense scenarios, and the 4.1-inch barrel limits velocity to about 1050 fps with standard ammunition—inadequate for ethical hunting beyond small game at close range. If you need a suppressor host with higher capacity, consider the Stevens 334 in .308 Win for serious suppressed work.

What's in the box?

You get the pistol, two 10-round magazines, a threaded barrel adapter, and documentation—no optic plates or case included. The missing optic plates require separate purchase from Smith & Wesson (typically $40-60), which is disappointing at this $407.99 price point. The magazines feature a last-round hold-open and disassemble without tools, a nice touch for maintenance compared to some Stevens shotguns that omit basic disassembly tools.

Is the Smith & Wesson M&P 22X worth it at $407.99?

At $407.99, it's fairly priced for an optics-ready .22 LR with suppressor compatibility, but budget another $60 for optic mounting hardware. Compared to the $350 Taurus TX22, you're paying for the M&P pedigree and superior trigger, though both handle bulk ammo equally well. If you already own an M&P centerfire pistol and want identical manual of arms training, this is justifiable; if you just want a cheap plinker, look elsewhere.
