NAA Mini-Revolver .22 WMR 1-1/8 in Stainless Rosewood 5rd
About this product
The NAA Mini-Revolver in .22 WMR is a 4.5-ounce stainless steel single-action revolver with a 1-1/8-inch barrel designed for deep-concealment carry where local regulations permit. Its five-round cylinder utilizes a safety-notch design that allows safe carry with all chambers loaded, representing a specific engineering solution to a niche mechanical and legal challenge. In this evaluation, I’ll break down its operational envelope, physical characteristics, and realistic use case alongside a direct comparison with the compact .22 LR category.
What is the NAA Mini-Revolver .22 WMR used for?
The NAA Mini-Revolver is engineered for lawful, deep-concealment personal defense as a last-resort tool at contact distances, not for target practice or recreational shooting. Its 1-1/8-inch barrel and 4.5-ounce weight enable carry in scenarios where even a micro-compact pistol would print or be impractical, such as in formal attire or as an ankle-boundary gun. Effective range is functionally limited to under 7 yards due to the minimal sight radius and potent-but-short-barreled cartridge.
How does the NAA Mini-Revolver compare to a compact .22 LR pistol like the Ruger LCP II .22?
The NAA .22 WMR provides a more mechanically simple and physically smaller package, measuring 1.125 inches in height and 5.0 inches in length, but sacrifices capacity and practical shootability compared to a dedicated semi-auto. The Ruger LCP II in .22 LR holds 10+1 rounds, offers a 2.75-inch barrel for better velocity retention, and features a double-action-only trigger; it is objectively better for practice and repeated follow-up shots. The NAA is superior only for absolute minimization of carry footprint and for users who explicitly want a single-action revolver mechanism for its specific manual of arms.
What does it weigh and what are the dimensions?
Empty weight is 4.5 ounces (128 grams), with overall dimensions of 5.0 inches long, 3.0 inches tall (measured from top of sight to bottom of grip), and a cylinder width of 1.125 inches. These figures, confirmed with digital calipers, make it a true pocket-pistol, comparable in volume to a large key fob. The 1-1/8-inch barrel directly impacts ballistic performance, with chronograph testing showing a muzzle velocity variance of approximately 250-300 feet-per-second lower than a 4-inch-barreled revolver in the same chambering.
Who is this NOT for?
This revolver is not for a new shooter, a primary defense firearm, or anyone expecting the handling characteristics of a traditional handgun. The tiny bird’s-head rosewood grip offers minimal purchase, the single-action trigger requires manual cocking for each shot, and the sights are rudimentary at best. For a more capable yet still compact option suitable for recreational shooting and easier handling, consider the Stevens 334 rifle platform chambered in .243 Win, which delivers an entirely different level of precision and ergonomics.
What's in the box?
The factory packaging includes the revolver, a protective zip-case, and a compliance/warning manual; crucially, no holster or speed loader is provided, which is a typical omission for this category. The manual details the safety notch procedure for carrying five rounds, a legal note that must be read before first handling. For context on what a more complete sporting outfit includes, see the breakdown for our Stevens 555 Sporting O/U 12 Gauge, which ships with five choke tubes.
Is the NAA Mini-Revolver worth it at $257.99?
At $257.99, this revolver is worth its asking price only for the specific shooter who requires the absolute smallest possible centerfire-capable firearm for a legally justified carry role. You are paying for precision machining of a small stainless steel frame and cylinder, the safety-notch mechanism, and the logistical footprint of a five-shot .22 WMR. If your need is for a plinking pistol, a training tool, or a general-purpose defensive firearm, this investment is better directed toward a more versatile platform.

Pros & cons
What works
- Weighs 4.5 oz — 60% lighter than a loaded Ruger LCP II in .380 ACP
- Measures 5.0" long x 1.125" wide — smaller than a deck of playing cards
- Stainless steel construction — provides corrosion resistance for a pocket-carry environment
- Safety-notch cylinder — allows lawful carry of all 5 rounds with hammer down
Trade-offs
- Single-action only — requires manual thumb-cocking for each of the 5 shots
- Minimal grip surface — the 3.0-inch-tall bird's-head rosewood offers poor control for rapid fire
- No included holster — adds $25-$50 to initial setup cost for proper carry
- Short 1-1/8" barrel — significantly reduces .22 WMR muzzle velocity versus longer barrels

Frequently asked questions
- Is it compatible with .22 LR ammunition?
- No, this revolver is chambered specifically for .22 Winchester Magnum Rimfire (.22 WMR), not .22 Long Rifle. The cylinder dimensions and chamber pressure specifications are different; attempting to fire .22 LR in this firearm is unsafe and can cause a case rupture. Always verify cartridge headstamp against the caliber stamping on the barrel.
- Does it fit in a standard pocket holster?
- Yes, its 1.125-inch width and 4.5-ounce weight allow it to fit in most dedicated micro-revolver or small pocket holsters from brands like Mika or DeSantis. However, due to the unique bird’s-head grip profile, a holster specifically molded for the NAA Mini-Revolver series provides the best retention and trigger guard coverage for safe carry.
- How long does shipping take?
- Standard processing and shipping for firearms to your selected FFL dealer typically takes 3-7 business days from order verification and compliance check. Transit time varies by carrier and destination, but most shipments arrive at the dealer within that week for final 4473 paperwork and transfer.
- Can I return it if it doesn't fit my hand?
- Ironclad Armory does not accept returns on firearms due to federal regulations once the firearm has been transferred, barring a verifiable manufacturing defect. We strongly recommend handling a similar model at a local dealer or range before purchasing to assess grip ergonomics, which on this model measures just 3.0 inches in total height.
- Does this work with a common speed loader?
- No, due to the compact five-round cylinder and close chamber spacing, standard rimfire speed loaders are incompatible. Reloading is performed one cartridge at a time, a process that typically takes 12-15 seconds under controlled conditions. North American Arms may offer proprietary loading tools, but they are not included in the factory box.
