Description
There is small, and then there is the North American Arms 22MC. At just over 5 inches long and right around 6 ounces, this little five-shot single action disappears into a pocket in a way no other handgun really can. What sets the 22MC apart from the standard magnum mini is the second cylinder in the box. You get a .22 WMR cylinder for carry and a fitted .22 LR conversion cylinder for practice, so one gun covers both jobs without buying two.
Why the 22MC Convertible Earns Its Keep
The .22 Magnum cylinder runs all the popular WMR loads, including shot shells, which is why so many of these end up riding along on farms, trap lines, and fishing trips as a snake gun. Swap over to the long rifle cylinder and you can burn through bulk-pack ammo at the range for pennies a round. Cylinder swaps take a few seconds, no tools needed, just pull the cylinder pin and trade them out. The frame and barrel are stainless steel, so sweat and pocket lint are not going to give it fits, and the laminated rosewood bird's head grips give it a classic look that dresses up nicely.
Built for Real Pocket Carry
NAA's half-way notch cylinder is the detail that makes these minis practical. The hammer rests in a notch between chambers, fully off any live round, so you can carry all five loaded without worry if the gun takes a knock. The 1 5/8 inch barrel wears a fixed blade front sight paired with a simple rear notch, which is exactly right for the close-range work this gun is built for. Single action operation keeps the mechanism simple and dependable.
Who the NAA 22MC Makes Sense For
This is a deep-concealment backup, a tackle box companion, and a fun little plinker rolled into one. It is the standard other mini-revolvers get measured against, and there is a huge catalog of grips, holsters, and accessories that fit it. If you have been wanting an NAA mini, the convertible version is the one to get since the extra cylinder doubles what the gun can do.

Frequently Asked Questions
How do you switch cylinders on the NAA 22MC?
It only takes a few seconds and no tools. Remove the cylinder pin, drop out the installed cylinder, set the other one in its place, and reinsert the pin. The .22 LR conversion cylinder is made slightly longer specifically to fit the magnum frame, so both cylinders lock up properly.
Can I carry the 22MC with all five chambers loaded?
Yes, and that is one of the best features of the design. The cylinder has half-way notches between the chambers where the hammer rests completely off any live round. Lower the hammer into one of those notches and the gun can take a bump or a drop without risk of the hammer contacting a cartridge.
Can the North American Arms 22MC shoot .22 Magnum shot shells?
It can. The .22 WMR cylinder handles all popular .22 Magnum ammunition, including shot shell loads, which is why a lot of folks keep one of these around as a compact snake gun for hikes, yard work, and fishing trips.
Is the NAA 22MC single action only?
Yes, it is a true single action, so the hammer has to be cocked manually for every shot. That keeps the mechanism simple and reliable in a gun this small. It is meant as a close-range backup and utility revolver, and the fixed sights are set up with that role in mind.
