Features 

At 6.20 oz. and 5.25 inches overall, this revolver fits in a pocket or vest pouch without bulk. Stainless steel resists corrosion well and holds up to daily carry. Single-action operation means manually cocking the hammer before each shot. Half moon sights are minimal but functional at close range. The .22 WMR cartridge gives better velocity and energy than standard .22 LR from a short barrel.

The NAA Mini-Revolver appeals to shooters who want the smallest possible carry option. The size and weight -- 6.20 oz. and 5.25 inches -- is the primary draw, and owners regularly note how easily it disappears in a pocket or as a backup.

The stainless steel construction gets good marks for durability and corrosion resistance. Single-action operation is simple and straightforward. The five-round capacity and .22 WMR caliber are the main practical limitations discussed -- owners generally understand this is a last-resort or backup gun rather than a primary defensive arm. Some owners with larger hands note the grip size is tight. Overall sentiment is positive among buyers who know what it is and use it accordingly.
