What's Included
- North American Arms NAA-22M Mini-Revolver (.22 WMR)
The NAA-22M pairs micro dimensions with an all-stainless construction. The frame, cylinder, barrel, and receiver are stainless steel with a satin stainless finish for consistent corrosion resistance and a uniform look.
Its five-shot fluted cylinder is removable using a forward-pull knurled base pin, simplifying unloading and maintenance. The safety cylinder with hammer-rest notches allows the hammer to rest securely between chambers.
This revolver is single-action only with an exposed spur hammer and a stud-type trigger with no trigger guard, true to the ultra-compact pocket-revolver format. Fixed sights include a half-moon front and a grooved topstrap rear channel for a simple, durable sight picture.
Ergonomics are anchored by smooth wood birdshead grip panels that complement the micro size. With a barrel length of about 1 5/8 in and an unloaded weight around 6.5 oz, it is purpose-built for discreet carry and ease of handling in a minimalist package.
