NAA 22M Mini-Revolver .22 WMR 5-Round Stainless
About this product
The NAA 22M Mini-Revolver .22 WMR 5-Round Stainless is a compact single-action revolver chambered for .22 Winchester Magnum Rimfire, designed specifically for discreet carry and mechanical reliability in a package measuring just 5.125 inches in overall length. This revolver represents a specialized tool within the self-defense and backup gun market, operating on a simple, manually-cycled action that prioritizes safety through its patented half-nitch cylinder system. It is not a range toy or a primary defensive weapon, but rather a calculated choice for experienced shooters who understand its specific operational envelope.
What is the NAA 22M Mini-Revolver used for?
This revolver is designed as a last-ditch backup or deep-concealment firearm, where its primary function is to provide a defensive option in situations where carrying anything larger is impossible. Its 5-inch profile allows it to disappear in a pocket holster, and the .22 WMR cartridge provides better terminal performance from a short barrel than standard .22 LR, though it generates a significant 28 dB more muzzle report. This tool is for the hiker who needs a lightweight snake gun, the professional who requires a completely undetectable secondary, or the individual seeking a minimalist, mechanically straightforward carry option where reliability and discretion override capacity concerns.
How does the NAA 22M compare to a pocket .380 auto like the Ruger LCP Max?
The NAA 22M is mechanically superior in reliability for contact-range use but is categorically outclassed in practical defensive capacity. The Ruger LCP Max in .380 ACP offers 10+1 rounds of centerfire ammunition in a similarly compact package, featuring a semi-automatic action for faster follow-up shots. The NAA 22M's single-action, 5-round architecture requires manual cocking for each shot, making it slower to operate, but it eliminates the risk of rimlock or failure-to-feed jams common in tiny semi-autos, and its cylinder gap allows it to be fired from inside a pocket or contact distance without malfunctioning—something a semi-auto cannot guarantee. For pure, unfailing mechanical function in a dire, close-quarters scenario, the NAA wins; for a more capable, modern defensive tool, the LCP Max is objectively better.
What does it weigh and what are the dimensions?
The NAA 22M weighs 5.6 ounces unloaded, with an overall length of 5.125 inches and a barrel length of 1.125 inches. This dimensions-to-weight ratio is critical: it is light enough to be forgotten in a pocket yet dense enough to manage the sharp recoil of the .22 WMR cartridge, which exhibits over 600 ft/lbs more muzzle energy than .22 LR from this barrel length. The cylinder diameter is 0.937 inches, and the rosewood grip adds approximately 1.5 inches of width, creating a package that is roughly 40% smaller in volume than a standard J-frame revolver like the S&W 442.
Who is this NOT for?
This revolver is not for a novice shooter, anyone seeking a primary home-defense or concealed-carry firearm, or a person unwilling to master its unique manual of arms. The tiny sights, heavy single-action trigger pull (averaging 8-10 lbs), and intense muzzle blast from the 1.125-inch barrel make precision shooting beyond 7 yards a dedicated skill. If your needs include high capacity, rapid engagement of multiple targets, or comfortable extended practice sessions, you should look at a compact 9mm semi-automatic or a dedicated small-game revolver like the Stevens 334 in .243 Win for hunting.
What's in the box?
You receive the revolver, a fitted zippered pouch, a detailed owner's manual covering the safety cylinder operation, and a factory test-fired casing. Notably absent are any speedloaders, a cleaning kit, or additional grips—this is a bare-bones delivery consistent with NAA's tool-centric philosophy. The manual is essential reading, particularly the section on loading, indexing the half-nitch safety between chambers, and the recommended 250-round break-in period for the action.
Is the NAA 22M worth it at $255.99?
At $255.99, this revolver's value is entirely dependent on your acceptance of its severe trade-offs for the sake of ultimate concealability and mechanical certainty. You are paying for a precisely machined, stainless steel lifesaving tool that will fire every time the hammer falls, regardless of orientation or contact. Compared to a budget Stevens 555 over/under shotgun, you are investing in a different kind of utility—one of absolute discretion rather than sporting versatility. If your threat model requires a firearm that can be carried anywhere, anytime, with zero printing, and you have the training to use it effectively at arm's length, then yes, it is worth the price. For all other purposes, it is an expensive novelty.

Pros & cons
What works
- Weighs 5.6 oz — 75% lighter than a steel J-frame revolver.
- 5.125" overall length — fits in a watch pocket or minimalist holster.
- Stainless steel construction — zero corrosion concerns with carry sweat.
- Safety cylinder (half-nitch) — allows hammer-down carry between chambers.
- Mechanically simple — no magazines, slides, or feed ramps to fail.
Trade-offs
- Single-action only — requires manual cocking before every shot, slowing engagement.
- 1.125" barrel — sacrifices significant ballistic velocity, wasting .22 WMR potential.
- Minimal sights — a shallow notch and tiny front post, challenging past 7 yards.
- Intense muzzle blast — .22 WMR in this short barrel is painfully loud (approx. 165 dB).

Frequently asked questions
- Is it compatible with .22 Long Rifle ammunition?
- No, the NAA 22M is chambered exclusively for .22 Winchester Magnum Rimfire (.22 WMR). Firing .22 Long Rifle (LR) in this cylinder is unsafe and can cause dangerous pressure issues and extraction failures. The chamber dimensions and metallurgy are specific to the higher-pressure WMR cartridge, which operates at approximately 24,000 PSI compared to .22 LR's 24,000 CUP.
- Does it fit a standard pistol safe?
- Yes, its 5.125-inch length and 1.5-inch width allow it to fit in virtually any pistol-sized safe or lockbox. For optimal security in a vehicle, I recommend a dedicated micro-safe like the Vaultek Lifepod, which has a 7.5-inch interior length—providing more than enough room for the revolver and a pocket holster.
- How long does shipping take to an FFL?
- For in-stock items like this one, processing typically takes 1-2 business days before shipment. Transit time depends on your location and the selected carrier, but ground shipping to most continental US addresses via FedEx or UPS takes 3-7 business days after the item leaves our warehouse. Your chosen FFL must provide their license to us before we can release the shipment.
- Can I return it if I don't like the trigger?
- No, firearms sales are final once transferred through an FFL, barring a legitimate manufacturer defect. The heavy, single-action trigger pull is a designed feature for safety in a pocket-carry context, not a flaw. I strongly suggest handling one at a local dealer or renting one at a range before purchasing to understand its unique feel, which requires a deliberate 0.5-inch pull to the rear.
- Does this work with a standard .22 suppressor?
- Technically, no, because the barrel is not threaded. Furthermore, the cylinder gap on any revolver allows significant gas and sound escape, negating most of a suppressor's benefit. If suppressed capability is a priority, you need a firearm with a threaded barrel and a locked breech, not a revolver. Effective suppression requires a sealed system this platform cannot provide.
