Features 

 
The .22 WMR chambering gives the Wasp more energy than the .22 LR version of the same platform, which matters when this is carried as a backup. At 6.5 oz and 5.13 inches overall, it tucks away in a pocket easily. The stainless finish resists corrosion well in daily carry conditions. The pebbled rubber grip provides better purchase than smooth wood on a pistol this small. The half-moon sight aids quick target acquisition at close range. 
 

Usage 

 
The Wasp is primarily a deep-cover backup or a trail gun for outdoor activities where minimal size and weight are the priority. The .22 WMR caliber is more capable than .22 LR for the role. It also works for casual range sessions and plinking.

The NAA Wasp in .22 Magnum earns consistent appreciation for its size and stainless finish. At 6.5 oz it is genuinely pocketable, and the corrosion resistance of the stainless construction is practical for daily carry in varied weather.

The .22 WMR caliber gets a more divided reception than the .22 LR version. Some users appreciate the step up in energy over .22 LR while maintaining manageable recoil, making it more accessible for less experienced shooters. Others remain skeptical about stopping power for defensive use and suggest it works best as a backup rather than a primary defensive option.

Grip ergonomics are mentioned frequently. The pebbled rubber grip works, but the small size can make the revolver awkward for larger hands during extended shooting. The five-round capacity is seen as a limitation in any serious defensive scenario. Reliability is generally reported as good, with occasional extraction issues mentioned as something to watch for during extended range sessions.
