Description
The North American Arms 22MC-P Ported is the company’s 1-5/8 inch mini-revolver with a functionally ported barrel and two cylinders: one for 22 WMR and one for 22 LR. It is a tiny stainless five-shooter made in Provo, Utah, for deep-pocket backup and fun at the range.

North American Arms 22MC-P Ported Overview
This convertible model is listed by NAA as model NAA-22MC-P (UPC 744253002175). It carries five rounds, measures about 5.1 inches overall according to distributor data, and weighs roughly 6.5 ounces. Construction is stainless steel with wood bird’s-head grips and fixed sights. The ported barrel and the second cylinder are what separate it from the plain 22M, and that combination makes it one of the most versatile guns in the mini-revolver catalog.
Loading and Carry
Like every classic NAA mini-revolver, the 22MC-P is a single-action design: you thumb the hammer back for each shot, and the trigger only releases it. To load, you pull the cylinder pin, lift the cylinder out of the frame, load or unload it off the gun, and reinstall it. That is slow by design, so treat the five rounds in the cylinder as all you have. Between the chambers are safety notches, and the hammer should rest in one of them for carry, exactly as the owner’s manual describes.

What the Porting Does
Ports cut near the muzzle vent some gas upward when the 22 Magnum cylinder is fired, which helps hold down muzzle rise on a gun this light. The effect is modest but real on fast follow-up shots. The trade-off is more noise and flash at the ports, so wear hearing protection and keep your support hand well behind the muzzle. With 22 LR loaded, the porting has very little effect at all.
Two Cylinders, Two Jobs
The 22MC-P ships with two cylinders. The 22 WMR cylinder is for carry and serious use, and the 22 Long Rifle cylinder lets you practice for far less money with quieter, milder ammunition. Swap cylinders only with the gun unloaded, never mix cartridges between them, and remember that 22 LR from a barrel this short is a practice and plinking load. Both kinds of ammunition can be hard to find at times, so stock up when your preferred loads are available.

Living With a Mini-Revolver
Be realistic about what a tiny rimfire revolver does well. The 22MC-P is loud for its size, flash is heavy in low light, and sights are minimal, so practical accuracy is measured in a few yards for most shooters. Rimfire ignition is less certain than centerfire, which is one more reason to test your carry ammunition. Use a proper holster that covers the trigger area; loose in a pocket is not acceptable.
Why the Convertible Ported Version
Shoppers usually compare this gun with the magnum-only 22M-P and with the shorter 1-1/8 inch 22MSC-P. The 22MC-P keeps the longer barrel for a little more velocity and a slightly longer sight radius, adds the porting, and includes the 22 LR cylinder for cheap practice. If you want one mini that can do everything, this is the configuration to buy.
State Laws and Ownership
Pennsylvania buyers complete a standard handgun transfer with a PICS check at the receiving dealer, and carrying concealed outside your home or vehicle generally requires a License to Carry Firearms. Some states keep approved-handgun rosters (California and Massachusetts are the best-known examples) and may not allow the NAA 22MC-P Ported; New York, New Jersey and several cities add permit steps of their own. Check your state and local rules before ordering, because we cannot transfer a handgun into a jurisdiction that prohibits it.
