The North American Arms Mini-Revolver in .22 WMR is a single-action, 5-shot revolver built from stainless steel with wood grip panels. At 5.9 ounces and 4.75 inches overall with a 1.125-inch barrel, it's about as small and light as revolvers get. Fixed sights keep the design simple and snag-free.

Detailed Features 

The single-action mechanism means the hammer must be manually cocked before each shot, which makes every round deliberate. Stainless construction resists corrosion and handles the moisture that comes with daily carry. The wood grips fill the hand without adding much bulk. 
 

Usage Scenarios 

This is a pocket or backup carry gun and a trail companion for people who want something light. The .22 WMR cartridge gives it more punch than .22 LR out of a short barrel, though it's still a small caliber. It also gets used at the range as a novelty and for practice with single-action mechanics.

The NAA Mini-Revolver gets credit for doing exactly what it advertises: it's tiny, light, stainless, and reliable. Owners who carry it as a backup or pocket gun appreciate that it disappears in a pocket and doesn't rust. The single-action operation is seen as a plus by people who want intentional, deliberate shots rather than a quick-trigger double-action.

The criticism centers on the five-round capacity and the caliber. Some users question whether .22 WMR is adequate for defensive use, and five rounds leaves little room for error. The grip size is also a consistent topic — shooters with larger hands find it hard to shoot accurately, and the tiny frame makes it genuinely challenging to shoot well at any distance. That said, most owners who buy it knowing what it is remain satisfied. It occupies a niche and fills it well.
