Detailed Features 

 
The all-stainless build handles daily carry and weather exposure without corroding. The rosewood birdshead grip fills the hand reasonably well for such a small revolver and provides some purchase during the single-action firing sequence. Half-moon sights are minimal but functional at the close distances this gun is designed for. The single-action mechanism requires manual hammer cocking before each shot, which is a deliberate design choice for a gun this small. 
 
At 4 oz, it disappears in a pocket or as a backup carry piece.

The NAA MiniRevolver in .22 Short draws a consistent set of reactions from owners, most of them positive within clear expectations for what the gun is.

Concealability is the main appeal. Owners regularly note that the 4 oz weight and 3.63-inch length allow it to go places no other gun can — deep pocket carry, backup to a backup, or situations where any visible printing is unacceptable. The stainless construction holds up well to the pocket lint and occasional moisture that comes with deep concealment.

The rosewood birdshead grip is appreciated aesthetically and functionally. The gun looks good and the grip does what it needs to for a 5-shot .22 Short.

The caliber and capacity limitations come up in every discussion. .22 Short is not a primary defensive cartridge by any reasonable standard, and 5 rounds is minimal. Most owners acknowledge this openly — the gun is a last-resort or backup piece, not a primary carry option. Accuracy at distance is also limited by the 1.13-inch barrel, which is expected.

The single-action mechanism requires cocking for each shot, which some find slow under stress. For the use case this gun is designed for, most owners accept the trade-off. It occupies a niche that no other production gun fills quite the same way.
