Features 

 
At 4.6 ounces and 5.25 inches overall, the Wasp is one of the most compact carry options available. The vented barrel helps with heat dissipation during repeated firing. The safety cylinder / half-notch system prevents accidental discharge during carry. The bead front sight allows fast target acquisition within realistic engagement distances. 
 

Usage 

 
The Wasp is primarily a pocket carry or backup option. Its size makes it easy to carry daily and simple to store securely at home. At .22 LR, recoil is negligible, which suits newer shooters or anyone who wants to practice fundamentals without fatigue. It also works as a trail gun for outdoor activities where a small, light sidearm is useful.

Owners of the NAA Wasp in .22 LR consistently appreciate its size and weight: at 4.6 oz it disappears in a pocket, and the stainless finish holds up well in varied conditions.

The simplicity of the design is a recurring positive. No complicated mechanisms, minimal learning curve, and the single-action trigger is easy to manage. Most owners enjoy shooting it at the range and find the trigger pull acceptable.

Stopping power and capacity are the two honest drawbacks that come up regularly. Five rounds of .22 LR is thin for a primary defensive role, and there is genuine skepticism in the community about the caliber's effectiveness in serious self-defense situations. Accuracy at distance also gets mixed remarks: the 1.63-inch barrel limits the useful range, and some users find it harder to shoot precisely beyond a few yards. Occasional extraction issues come up in longer sessions, and a break-in period is sometimes recommended.
