Also known as: NAA-22LR, North American Arms Mini-Revolver, NAA Mini
Overview
The NAA Mini Revolver is an extremely compact single-action revolver chambered in .22 Long Rifle, built almost entirely from 17-4 PH stainless steel. Weighing roughly 4.5 ounces with a 1.125-inch barrel and a five-round cylinder, it is one of the smallest production firearms in the world. The design descends from a Freedom Arms mini-revolver that North American Arms acquired the rights to in 1990, and its thumb-cocked single-action lockwork pays homage to the early Smith & Wesson Model 1 rimfire revolvers. It is marketed primarily as a deep-concealment backup and last-ditch self-defense gun.

The cylinder must be removed from the frame for loading and unloading. Many models feature a safety cylinder with notches between the chambers, allowing the hammer to rest safely between live rounds.
Background
Often described as among the smallest commercially produced firearms in the world, the NAA Mini Revolver has become an icon of deep-concealment carry, small enough to vanish in a pocket or be built into a belt-buckle holster.
