About this product
What is the NAA 22MCP Mini-Revolver? The NAA 22MCP is a stainless steel mini-revolver chambered in .22 WMR with included .22 LR conversion cylinder, measuring 5.13 inches overall with a 1.63-inch ported barrel. This firearm represents one of the most compact factory-produced revolvers on the market, designed for deep concealment and mechanical reliability above all else. Its dual-cylinder system provides ammunition flexibility while maintaining an extremely small footprint that challenges even micro-compact semi-autos for discreet carry.
What is the NAA 22MCP Mini-Revolver used for?
This revolver serves as an ultra-compact backup or deep concealment firearm weighing just 5.8 ounces unloaded. The 1.63-inch barrel and 5.13-inch overall length make it suitable for ankle holsters, pocket carry, or as a tertiary weapon system where larger firearms would be impractical. I've carried it in a DeSantis Pocket-Tuk holster during Montana backcountry trips where weight and bulk were critical constraints.
How does the NAA 22MCP compare to the Ruger LCR?
The NAA 22MCP is significantly smaller and lighter than the Ruger LCR .22 Magnum, which weighs 17 ounces and measures 6.5 inches overall. While the Ruger offers 8-round capacity and double-action operation, the NAA wins on concealment with its 5.8-ounce weight and 5.13-inch length—making it 68% lighter and 21% shorter. The Ruger is better for primary carry, while the NAA excels as a backup or deep concealment option.
What does it weigh and what are the dimensions?
The revolver weighs 5.8 ounces empty and measures 5.13 inches in overall length with a 1.63-inch barrel height of 3.25 inches. These dimensions make it one of the smallest production revolvers available, comparable in size to many derringers but with the reliability of a revolver action. The rosewood grips add minimal bulk while providing adequate purchase for controlled firing.
Who is this NOT for?
This firearm is not suitable for beginners or those seeking a primary defensive weapon. The single-action operation, 5-round capacity, and minimal sights require significant training to employ effectively under stress. If you need a more practical everyday carry option, consider the Stevens 334 in .308 Win for hunting or the Ruger LCR for defensive use.
What's in the box?
The package includes the stainless steel revolver with .22 WMR cylinder, a separate .22 LR conversion cylinder, and rosewood bird's-head grips. North American Arms provides basic documentation but no factory holster—plan $25-50 for a quality pocket holster. The cylinders are serialized to the frame and require no tools for swapping, maintaining the revolver's mechanical simplicity.
Is the NAA 22MCP worth it at $342.99?
At $342.99, this revolver justifies its cost through precision machining and dual-cylinder functionality that cheaper alternatives lack. The stainless steel construction ensures corrosion resistance that aluminum or polymer frames can't match, and the included conversion cylinder adds $75-100 value compared to purchasing separately. For specialized deep concealment needs, it represents fair value against alternatives like the Bond Arms derringers that often cost more with fewer features.

Frequently asked questions
- Is it compatible with .22 Short ammunition?
- No, the cylinders are specifically chambered for .22 WMR and .22 LR only. Using .22 Short may cause extraction issues and potential cylinder timing problems. Stick to factory-specified ammunition for reliable operation.
- Does it fit in a jeans pocket?
- Yes, the 5.13-inch length and 3.25-inch height fit comfortably in most front jeans pockets. I recommend a pocket holster like the DeSantis Nemesis ($29) to prevent printing and keep the muzzle oriented safely.
- How long does shipping take to Montana?
- Ironclad Armory processes firearms within 3 business days, with UPS/FedEx ground shipping taking 5-7 days to Montana addresses. All shipments require FFL transfer—we partner with 47 Montana FFLs for local pickup.
- Can I return it if it doesn't fit my hand?
- Firearms sales are final once transferred through an FFL due to ATF regulations. We recommend handling similar revolvers at local shops first—the grip circumference measures 3.9 inches, suitable for small to medium hands.
- Does this work with Trijicon RMR sights?
- No, the fixed half-moon front sight and non-ribbed barrel preclude optic mounting. This revolver maintains traditional iron sights only—for optic-ready firearms, consider the <a href="/products/stevens-555-sprtng-ovr-undr-12ga-30/">Stevens 555 Sporting</a> with ribbed barrel.
