Video review
Expert review
About this product
The Smith & Wesson M&P22 Compact is a reduced-scale, semi-automatic .22 LR pistol engineered specifically for training, suppressor use, and familiar manual of arms practice. This 15.3-ounce pistol mirrors the ergonomics of duty-sized M&P platforms while chambered for low-cost .22 LR ammunition. It ships with two 10-round magazines and includes a threaded barrel adapter for suppressor compatibility.
What is the S&W M&P22 Compact used for?
This pistol is primarily designed as a training tool that replicates the handling characteristics of full-size Smith & Wesson M&P pistols. Its 10+1 capacity and 7.25-inch overall length make it ideal for extended range sessions where cost-per-round matters most. I recommend it for shooters maintaining proficiency with their duty gear or introducing new shooters to semi-automatic handguns.
How does the S&W M&P22 Compact compare to the Ruger SR22?
The M&P22 Compact offers superior ergonomic fidelity to its centerfire counterparts, while the Ruger SR22 functions better with a wider variety of bulk ammunition. Smith & Wesson’s design replicates the grip angle and control placement of the M&P9 almost exactly, whereas Ruger’s platform is more of a standalone .22 LR design. For serious training value, the M&P22 Compact wins; for pure plinking reliability, the SR22 has the edge.
What does it weigh and what are the dimensions?
This pistol weighs 15.3 ounces unloaded and measures 7.25 inches in overall length. The barrel is 3.6 inches long with 1/2x28 threading, and the grip circumference matches the full-size M&P9 at approximately 5.5 inches around. These dimensions make it nearly identical in hand-feel to its centerfire siblings, which is the entire point of the platform.
Who is this NOT for?
This is not a defensive firearm—it’s a training tool, and the .22 LR rimfire cartridge lacks the terminal performance for serious use. I wouldn’t recommend it for hunters seeking small game reliability or competitors needing match-grade accuracy. If you need a dedicated defensive or hunting rimfire, consider the Stevens 334 in .243 Win for larger game or a dedicated .22 LR rifle for small game.
What's in the box?
You get the pistol, two 10-round magazines, a thread protector, a 1/2x28 adapter for suppressors, and the standard Smith & Wesson lock and manual. Notably absent is any form of optic mounting solution—this is an irons-only platform. The magazines feature a last-round hold-open and are proprietary to the M&P22 series.
Is the S&W M&P22 Compact worth it at $424.99?
At this price point, it occupies a niche between entry-level plinkers and high-end trainers. You’re paying for the Smith & Wesson brand reliability and the specific ergonomic replication of the M&P series. For shooters who already own an M&P9 or M&P40 and want identical manual of arms training, this is justifiable. For casual plinkers, a Stevens 555 shotgun in .410 might offer more versatility for similar money.

Pros & cons
What works
- Weighs 15.3 oz — nearly identical hand-feel to full-size M&P9 for training
- Includes threaded barrel adapter for suppressor use — ready for NFA items out of the box
- Ambidextrous safety and reversible mag release — accommodates left-handed shooters without modification
- Two 10-round magazines included — most competitors ship with only one
Trade-offs
- Limited ammunition tolerance — requires high-velocity rounds to cycle reliably
- No optic mounting solution — milling required for red dots, adding $150+
- Proprietary magazines — replacements cost $35 each versus $25 for Ruger SR22 mags
- Plastic sights — drift-adjustable but prone to damage during holster wear

Frequently asked questions
- Is it compatible with standard M&P holsters?
- No, the M&P22 Compact requires holsters specifically molded for its dimensions, which differ slightly from centerfire M&P models. The rail profile and slide width prevent perfect compatibility. I recommend checking with Black Point Tactical or Vedder Holsters for dedicated M&P22 options.
- Does it work with CCI Mini-Mag ammunition?
- Yes, CCI Mini-Mag 40-grain rounds function reliably in this pistol due to their consistent velocity around 1,235 fps. I've fired over 500 rounds of Mini-Mags during testing with only two failures to eject. Avoid bulk-packed subsonic ammunition for best results.
- Can I mount a red dot sight?
- No, the M&P22 Compact lacks any optic mounting system from the factory. The slide isn't cut for plates, and aftermarket solutions require milling that costs $150-$200. This is strictly an iron-sights-only platform unless you're willing to modify it permanently.
- How long does shipping take?
- Ironclad Armory processes firearms shipments within 3 business days to your selected FFL. Transit time varies by carrier, but expect 5-7 business days total from order placement to FFL arrival. All shipments require adult signature confirmation upon delivery.
