Features 

 
At 6.2 oz and 1.625 inches of barrel, this is one of the smallest production revolvers available. The stainless steel construction resists corrosion and holds up to pocket carry better than blued steel alternatives. The dual-caliber capability means you can swap between .22 LR for economical practice and .22 WMR for more energetic performance. Fixed sights and rubber grips are standard. Single-action operation means the hammer must be cocked manually before each shot. 
 

Usage 

 
The Mini Revolver is carried in pockets, vests, and as a backup where full-size pistols are impractical. The five-round capacity and single-action operation make it a deliberate, slow-shooting firearm by design -- it's not set up for rapid fire. Most owners choose it for deep concealment backup or as an introductory revolver for new shooters working with low-recoil ammunition.

The NAA Mini Revolver generates a predictable split in forum discussions: people who understand exactly what it is tend to like it; people expecting pistol-level performance are disappointed.

On the positive side, owners consistently praise the size and weight. At 6.2 oz it disappears in a pocket or vest, and the stainless finish holds up to years of carry without issues. The dual-caliber feature is appreciated as genuine versatility, especially for owners who practice with .22 LR but load .22 WMR for carry. Reliability with both calibers gets positive mention. The price sits below most semi-automatic pocket pistols, which factors into purchase decisions.

Criticism tends to cluster around capacity and recoil. Five rounds of .22 WMR from a 1.625-inch barrel is a limited defensive proposition, and the forum debate about .22 caliber for self-defense is ongoing and divided. The single-action mechanism means slow follow-up shots, which some owners find limiting. Sight picture at the short barrel length and the challenges of accurate shooting under stress are also discussed. Some owners report extraction issues with certain ammunition brands.
