Description
There is small, and then there is North American Arms small. The NAA 22M Mini-Revolver is one of the tiniest .22 Magnum handguns you can buy, built entirely from stainless steel with a 1.625 inch barrel and a five-shot cylinder. Weighing just a few ounces, it rides in a pocket, a boot, or a belt holster without ever announcing itself. Despite the size, this is no novelty piece. NAA has been machining these little revolvers in Utah for decades, and they have earned a solid reputation for tight fit and dependable function.
How the 22M Mini-Revolver Handles Carry
The standout feature on every NAA mini is the safety cylinder. Between each of the five chambers there is a halfway notch machined into the cylinder, and once you load up, you lower the hammer into one of those notches. That lets you carry all five rounds with zero worry about the hammer sitting over a live primer. When you cock the hammer, the cylinder rotates to the next chamber and you are ready to go. It is a simple, mechanical solution that has worked for generations of single-action carriers, refined for a gun you can hide in a closed fist.
Shooting the NAA 22M
This is a single-action revolver, so you thumb the hammer back for each shot, just like the cowboys did. The fixed half-moon front sight keeps things simple at close range, and the laminated rosewood bird's head grip settles the gun into your hand better than you would expect from something this compact. The .22 WMR cartridge gives you a real step up in energy over .22 LR out of a short barrel, and the gun runs fine with the full range of .22 Magnum loads, including shotshell rounds that make it a handy trail companion for snake country. If you want cheaper range time, NAA offers a .22 LR conversion cylinder that drops right in.
Whether it ends up as a deep-concealment backup, a tackle box gun, or just a conversation starter at the range, the 22M is a well-made piece of American gunmaking that punches way above its size.

Frequently Asked Questions
Can the NAA 22M be carried with all five chambers loaded?
Yes, and that is one of its best features. The cylinder has halfway notches machined between each chamber, so after loading you lower the hammer into one of those notches instead of resting it on a live round. When you cock the hammer to fire, the cylinder rotates to the next chamber, giving you all five shots without compromising safe carry.
Can I shoot .22 LR through the 22M Mini-Revolver?
Not through the factory cylinder, since it is chambered specifically for .22 WMR. North American Arms does offer a .22 LR conversion cylinder that swaps in easily, which is a popular add-on for cheaper practice sessions. If you want both from the start, NAA sells the same gun bundled with the conversion cylinder as the NAA-22MC.
How do you reload the NAA 22M?
Reloading is a deliberate process, true to old-school single-action design. You pull the base pin, remove the cylinder entirely from the frame, and use the pin to push out spent cases before dropping in fresh rounds. It is not a speed reload setup, but for a deep-carry backup or trail gun, that trade-off buys you an incredibly small package.
Will the 22M handle .22 Magnum shotshells for snakes?
Yes, the 22M runs the full range of popular .22 WMR ammunition, including shotshell loads often sold as snake shot. That versatility makes it a favorite for hikers, anglers, and anyone working around the property where a close-range pest load comes in handy.
