North American Arms

North American Arms is a United States company, headquartered in Provo, Utah, that manufactures small pistols and mini-revolvers. The company was originally named Rocky Mountain Arms. It was not until a couple of years later that they changed the name to North American Arms.

Mini revolvers
The mini-revolvers produced by the company are single action revolvers, which have a spur trigger design. They are reminiscent of late 19th century pocket revolvers, the main differences being their size and also that NAA's mini-revolvers are made completely of stainless steel. The design of the mini-revolvers was developed by Freedom Arms, which stopped selling these mini-revolvers in 1990 and sold the design to North American Arms.

Mini-Revolvers are made in the following calibers:
 * .22 Short
 * .22 Long Rifle
 * .22 Winchester Magnum Rimfire
 * .22 Black powder cap and ball

Semi-automatics
Semi-automatics are made by North American Arms in the following calibers:


 * .25 NAA
 * .32 ACP
 * .32 NAA
 * .380 ACP

The .25 NAA cartridge was developed by North American Arms based upon a wildcat bottleneck cartridge using .32 ACP brass necked down to grip a .25 caliber bullet, with the goal of increasing penetration beyond what either a .25 ACP or .32 ACP could do. Likewise, the .32 NAA was developed by North American Arms to increase the penetration of a .32 caliber bullet relative to a .38 ACP cartridge.
