About
What it is, and why it matters
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.
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.
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.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
