The North American Arms Wasp is a .22 LR single-action mini-revolver built for deep concealment. At 6.20 oz and 4.63 inches overall length, it's one of the smallest functional revolvers on the market.

Detailed Features 

The 1.13-inch barrel and 4.63-inch overall length make this one of the most concealable revolvers available. The rubber pebbled grip provides a reasonable hold given the small frame. Single-action operation requires cocking the hammer for each shot, which is a deliberate process rather than a quick-draw design. 
 
The bead front sight is functional but limited at any real distance. At this size and caliber, the Wasp is intended for close-range backup use, not primary defense. The stainless steel frame resists corrosion — a practical advantage for a gun that may be carried in a pocket or bag for extended periods. 
 

Usage Scenarios 

• Backup Carry: Its size allows carry in locations where larger guns won't fit. 
• Field Use: Lightweight enough to add to a pack without consequence; useful for pest control. 
• Range Introduction: Low recoil in .22 LR makes it approachable for new shooters, though the small grip takes some getting used to.

The NAA Wasp draws consistent feedback centered on its size — people either specifically want the smallest possible revolver and are satisfied, or they find the limitations frustrating. Those who buy it knowing what it is tend to be happy with it.

The stainless steel build and compact dimensions are the most appreciated features. Shooters who carry it as a backup or deep-concealment option report that it does that job well. The .22 LR recoil is light, which makes it easy to shoot accurately at close range.

The criticisms are predictable: 5-round capacity, limited stopping power, and single-action operation that slows follow-up shots. Most users are clear that this isn't a primary defensive firearm. The consensus tends to position it as a backup option or specialized carry gun rather than a standalone defensive solution.
