The North American Arms Wasp Snub Nose is a single-action mini revolver chambered in .22 WMR with a 1.13-inch barrel. At 6.2 oz and 4.63 inches overall, it's one of the smallest revolvers NAA makes. The stainless steel frame and barrel are standard across the NAA line, and the black pebbled rubber grip gives slightly better traction than wood on a gun this small. Capacity is 5 rounds.

  At 1.13 inches the barrel is short even by mini revolver standards. This is a deep concealment or last-ditch backup gun, not a range pistol. The .22 WMR caliber has more energy than .22 LR but limited effectiveness beyond close range from this barrel length. Reloading single-action is slow. NAA's standard build quality applies here -- well-finished stainless with solid fit.

The NAA Wasp in .22 WMR gets the same type of feedback as other NAA mini revolvers: appreciation from buyers who understand the format, criticism from those who expected more from a defensive firearm.

The positives are consistent. The stainless construction is praised for durability and finish quality. The 6.2 oz weight and 4.63-inch overall length make it genuinely easy to pocket. Simple operation is valued by buyers who want a minimal-maintenance backup gun. The .22 WMR round is more capable than .22 LR, which some owners cite as sufficient for close-range defensive scenarios.

The criticisms center on the format's real limitations. Five rounds of single-action .22 WMR from a 1.13-inch barrel is a specific tool, and some buyers discover after purchase that the recoil is more noticeable than expected on a 6.2 oz frame. The bead front sight is difficult to align quickly. Compared to larger firearms the capacity is low. Price comes up occasionally as a friction point relative to capabilities.

The Wasp suits buyers who specifically need something this small -- pocket carry where nothing larger is practical, or as a true last-resort backup. Buyers expecting general-purpose defensive performance will find the format limiting.
