Description
Fifty years is a long run for any gun maker, and North American Arms decided to celebrate the right way: with a dressed-up version of the mini-revolver that built their reputation. This limited-edition .22 WMR model wears "50th Anniversary" scroll engraving across its matte stainless frame, paired with glossy black pearl grips set off by a gold NAA medallion. It catches light in a way the standard models never will, but underneath the fancy clothes it is the same rugged little five-shot that people have trusted in pockets since 1975.
Built on the Proven NAA Mini-Revolver Platform
Everything that makes the standard 22M a favorite carries over here. The frame, cylinder, and 1.63 inch barrel are precision machined from stainless steel, the action is a simple single-action design with an exposed hammer, and the fixed half-moon front sight keeps the profile snag-free. The .22 Magnum chambering gives you noticeably more pop than .22 LR out of a gun this size, and recoil stays entirely manageable. Loading is classic NAA: pull the cylinder pin, drop the cylinder out, load your five rounds, and reassemble. The hammer rests in safety notches machined between the chambers, so you can carry all five stoked without the hammer sitting over a live round.
Why This 50th Anniversary Edition Stands Out
Commemorative guns come and go, but this one has real staying power. NAA has been making mini-revolvers in Provo, Utah for half a century, and an engraved factory anniversary model tied to that milestone is the kind of piece that tends to get handed down rather than traded off. Whether it lives in a display case, rides along as a deep-concealment backup, or does a little of both, it earns its spot. If you have been meaning to add an NAA mini to the collection, this is the one to grab, because once the anniversary run is gone, it is gone for good.

Frequently Asked Questions
Can the 50th Anniversary Mini-Revolver also fire .22 LR?
Not as it ships. This model is chambered specifically for .22 WMR, and .22 LR should not be fired from a Magnum cylinder. NAA does make a .22 LR conversion cylinder that fits their Magnum frame minis, so that is an option if you want cheaper practice ammo down the road.
Is it safe to carry the NAA Mini-Revolver with all five chambers loaded?
Yes, when it is carried correctly. NAA machines safety notches into the cylinder between the chambers, and resting the hammer in one of those notches keeps it completely off any live round. That lets you carry a full five rounds safely, which is a big advantage over old-style single actions that had to be carried with an empty chamber.
Is this 50th Anniversary model a shooter or just a display piece?
Both, really. Mechanically it is the same proven stainless 22M platform NAA has built for decades, so it will run just fine at the range or as a deep-concealment backup. That said, it is a limited-edition commemorative with engraving and pearl grips, so plenty of buyers keep the round count low and treat it as a collectible.
How do you load and unload an NAA Mini-Revolver?
These load the old-school way. You remove the cylinder pin from the front of the frame, take the cylinder out of the gun, load or eject your rounds, then set the cylinder back in and reinsert the pin. It takes a little practice at first, but it becomes quick and second nature after a few range sessions.
