Description
The North American Arms 22M-P Ported is the straightforward 22 Magnum version of NAA’s 1-5/8 inch mini-revolver, with functional ports cut into the barrel. There is no second cylinder to keep track of, just a stainless five-shot revolver made in Provo, Utah.

North American Arms 22M-P Ported Overview
NAA catalogs this gun as model NAA-22M-P (UPC 744253002144). Distributor data lists a 1-5/8 inch barrel, about 5-1/4 inches overall length and roughly 6.5 ounces. It has stainless steel construction, wood bird’s-head grips and simple fixed sights. Because it is a magnum-only model, it costs a little less than the convertible 22MC-P and is the purer choice for people who will only ever carry it with 22 WMR.
Loading and Carry
Like every classic NAA mini-revolver, the 22M-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.

Ported Barrel Details
The ports vent part of the 22 Magnum blast upward to calm the small amount of muzzle flip this featherweight revolver produces. You will notice more concussion and flash at the ports than with the unported 22M, and that is worth knowing before you shoot it indoors or in dim light. Keep fingers of the support hand away from the front of the frame and the ports.
Ammunition
The 22M-P is chambered only for 22 WMR (22 Magnum). Never fire 22 LR, 22 Short or 22 WRF in it. Magnum rimfire costs more per round than 22 LR and supply can be uneven, so buy a few boxes of the load you trust and test it in your revolver. Short barrels give up a lot of the velocity printed on the box, and loads designed for short barrels tend to expand more reliably than rifle-oriented ammunition.

Living With a Mini-Revolver
Be realistic about what a tiny rimfire revolver does well. The 22M-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. A pocket holster that keeps the gun upright and covers the trigger is part of the purchase.
22M-P or the Convertible?
Pick this magnum-only model if you want the simplest package and will practice with the same 22 WMR you carry. If cheap practice matters more, the 22MC-P adds a 22 LR cylinder for a modest price difference. Compared with the shorter 22MS-P, the 1-5/8 inch barrel gives a bit more velocity and is a little easier to point, while the snub hides more easily as a backup gun.
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 22M-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.
