Description
The North American Arms 22MSC-P Ported pairs NAA’s shortest 22 Magnum barrel, just 1-1/8 inches, with functional porting and a spare 22 LR cylinder. It is about as small as a practical five-shot revolver gets, built in stainless steel in Provo, Utah.

North American Arms 22MSC-P Ported Overview
This model is NAA-22MSC-P (UPC 744253002168). Distributor specifications list a 1-1/8 inch barrel, roughly 4.75 inches overall, about 6.2 ounces, wood grips and fixed sights. It is the snub-nose sibling of the 22MC-P: the same frame and two-cylinder flexibility, with half an inch less barrel for an even smaller pocket footprint.
Loading and Carry
Like every classic NAA mini-revolver, the 22MSC-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.

Short Barrel, Real Trade-offs
With only 1-1/8 inches of barrel, 22 WMR loses a meaningful share of its rated velocity and throws a big fireball. The porting helps a little with muzzle flip, but it also adds blast near the frame. The short sight radius makes precise shooting harder, so practice at close distances and learn where the gun actually hits with your ammunition.
Two Cylinders
The 22MSC-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 22MSC-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.
Who Should Pick the Snub
Choose the 22MSC-P over the 1-5/8 inch 22MC-P when concealment matters most. It disappears into a small pocket holster or a vest pocket and still lets you do inexpensive plinking with the 22 LR cylinder. If you never plan to shoot 22 LR, the magnum-only 22MS-P is the leaner option.
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 22MSC-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.
