Description
There are small carry guns, and then there is the NAA Wasp. At around 6 ounces with a 1 1/8 inch barrel and an overall length under 5 inches, this stainless mini revolver rides in a pocket, a jacket, or a small pack without you ever noticing it. It is chambered in .22 WMR, which gives you a meaningful step up in velocity over .22 LR out of a gun this size, and the five-shot cylinder handles everything from standard magnum loads to shot shells for snakes on the trail.
What Sets the Wasp Apart from Other NAA Minis
North American Arms builds a whole family of mini revolvers, and the Wasp is the one with some flair. You get a vented rib over the barrel with a bead front sight, a skeletonized hammer, and a stylized cylinder and cylinder pin that give it a look all its own. The black pebbled rubber grip is a practical upgrade too, filling the hand better than slick wood panels and giving your fingers something to hang onto when you touch off a magnum round. Recoil is very manageable, and the whole package feels tighter and more finished than you might expect from something this tiny.
Carrying the NAA Wasp Loaded and Ready
Like every NAA mini revolver, the Wasp uses half-way notches machined between the chambers. Rest the hammer in one of those notches and you can carry all five chambers loaded without the hammer sitting over a live round. It is a simple, proven system that has been part of the NAA design from the start. Operation is classic single action: cock the hammer for each shot, and the cylinder removes for loading and unloading.
A Backup That Earns Its Keep
The Wasp works best as a deep concealment backup, a tackle box or trail companion, or just a fun little range piece that draws a crowd. It is built almost entirely of stainless steel, so sweat, rain, and pocket lint will not wear it down. If you want to shoot cheaper .22 LR through the same frame, NAA offers a convertible version with a conversion cylinder, but this model keeps things simple with a dedicated .22 Magnum setup.

Frequently Asked Questions
Can the NAA Wasp be carried with all five chambers loaded?
Yes. The cylinder has half-way notches machined between each chamber, so you can lower the hammer into a notch and carry it fully loaded with the hammer resting safely away from any live round. This is a signature feature across the NAA mini revolver line and one of the main reasons people trust these little guns for pocket carry.
Will this Wasp also shoot .22 LR ammunition?
This particular model, NAA-22MS-TW, is a dedicated .22 Magnum revolver and does not include a .22 LR cylinder. If you want to run both calibers, NAA makes a convertible version of the Wasp (NAA-22MSC-TW) that ships with a .22 LR conversion cylinder. This one keeps it simple with magnum only.
How do you load and unload the NAA Wasp?
Like all NAA mini revolvers, the Wasp loads by removing the cylinder from the frame. You pull the cylinder pin, drop the cylinder out, load your five rounds, then reinstall it and set the hammer in a safety notch. It takes a little practice at first, but it becomes second nature quickly.
Can I shoot snake shot through the Wasp?
Yes, the Wasp runs all popular .22 Magnum ammunition, including .22 Magnum shot shells, which some makers market as snake shot. That flexibility makes it a handy companion for hiking, fishing, and working around the property where slithering surprises show up.
