NAA Sidewinder NAA-SWC-250 | .22 WMR/.22 LR | 2.5 in

The North American Arms Sidewinder (NAA-SWC-250) is a compact, five-shot single-action revolver chambered for .22 WMR with a supplied .22 LR conversion cylinder. It pairs a 2.5-inch stainless barrel and frame with a rosewood bird’s-head grip and a conventional swing-out cylinder for simple loading and unloading. The Sidewinder is built for shooters who want a lightweight, small-frame revolver with caliber flexibility.

Typical applications include everyday carry (EDC) in jurisdictions and situations where a compact single-action is appropriate, and precision small-caliber target practice or small-game field use where low recoil and cartridge choice matter.
