The North American Arms Sidewinder is a single-action revolver chambered in .22 WMR. At 4.6 ounces and 4 inches overall, it's one of the smallest revolvers available. The folding holster grip is the distinguishing feature. It folds flat against the frame when not in use, which genuinely improves pocket carry and reduces printing compared to a fixed grip at this size.

Detailed Features 

The barrel is 1.125 inches, short even for a mini revolver. The half-moon fixed sights are simple and consistent. Stainless finish handles moisture and corrosion without special care. The single-action trigger is typical NAA: requires hammer cocking before each shot. 
 

Usage Scenarios 

• Personal carry: The folding grip and 4.6-oz weight make it genuinely pocketable for deep concealment or as a backup piece. 
• Recreational shooting: Low recoil in .22 WMR keeps range sessions easy, especially for newer shooters. 
• Small game: At close range, the .22 WMR is effective on small game where discretion matters.

The NAA Sidewinder gets polarized reactions that mostly come down to what the buyer expects from it.

The folding grip is the most-praised design element. Owners consistently note that it improves on-body carry versus fixed-grip NAA minis. The .22 WMR chambering is appreciated for keeping recoil minimal while still giving more energy than .22 LR. Build quality draws generally positive comments; the stainless construction feels solid for its size. The distinctive look is a conversation point. A lot of owners like that it doesn't resemble a conventional revolver.

On the critical side, accuracy at anything beyond close range is limited by the 1.125-inch barrel, which is something buyers should expect going in. The single-action-only trigger requires cocking before each shot, and some find that impractical in a defensive context. A few owners question whether .22 WMR is adequate for self-defense versus larger calibers, and that debate shows up regularly in forum threads. Price opinions are mixed. Most find it fair for what it is, though a handful feel alternatives offer better value.
