The NAA Mini Revolver is a single-action, 5-shot revolver chambered in .22 WMR / .22 LR with a 1.625-inch barrel. It weighs about 6.2 oz and is built entirely in stainless steel with rubber grips. At that size and weight it disappears in a pocket or on an ankle rig -- it's one of the smallest production revolvers available.

Detailed Features 

Single-action means you manually cock the hammer before each shot, which slows the rate of fire but gives a clean, consistent trigger press. The stainless frame resists corrosion and the rubber grips improve control given the small frame size. With a barrel that short, accuracy is limited to close range -- this is a contact-distance or very-close backup gun, not a target shooter. 
 
The revolver is simple to field-strip and has very few parts to fail, which is part of the appeal for a dedicated backup role. 
 

Usage Scenarios 

The Mini Revolver is most commonly carried as a deep-concealment backup or a trail gun for protection against small animals. It also works for casual plinking where minimal recoil is preferred. First-time owners should practice the single-action manual of arms -- including safe loading and the half-cock cylinder-rotation position -- before carrying it.

Owners of the NAA Mini Revolver in .22 WMR generally know what they're buying: a deep-concealment backup with real limitations. The stainless construction and rubber grips get consistently positive feedback, and the simplicity of the design means very little goes wrong mechanically. Most users find it reliable for what it is.

The 5-round capacity and single-action operation are the most common discussion points. Neither is a surprise given the platform, but shooters coming from semi-autos sometimes need time to internalize the slower manual of arms. Accuracy at anything beyond 10-15 feet is limited by the 1.625-inch barrel -- most owners accept this as a fundamental constraint of the format rather than a product flaw.

Recoil with .22 WMR is snappier than expected given the light weight, though still manageable. The mini revolver draws appreciation as a plinker at the range, where the novelty and low recoil make it genuinely fun to shoot. The main debate in owner communities is whether .22 WMR or .22 LR is the better choice for the intended role -- opinions split about evenly.
