North American Arms 22M50B 50th Anniversary 1.63" 5-Round Revolver

The North American Arms 22M50B 50th Anniversary .22 Magnum revolver is a purpose-built, ultra-compact defensive firearm designed for deep concealment and backup carry applications. Engineered for law enforcement professionals, armed security personnel, and civilians seeking dependable personal protection in a package that fits pocket, ankle, or off-body carry configurations, this miniature revolver delivers reliable performance without the bulk of full-size platforms. The 50th Anniversary edition honors NAA's legacy of precision manufacturing and represents over five decades of refinement in ultra-compact revolver design.

This five-round revolver chambers .22 Magnum ammunition—a bottleneck cartridge delivering superior ballistic performance compared to standard .22 LR while maintaining minimal recoil and muzzle rise. The 1.63-inch barrel optimizes velocity retention for defensive rounds while preserving the compact footprint critical to concealment. NAA's single-action mechanism features a fixed sight picture and stainless steel construction throughout, ensuring corrosion resistance and requiring minimal maintenance during extended carry. The miniature proportions—the smallest of all .22 Magnum revolvers—allow positioning in locations inaccessible to larger defensive tools, making it an ideal supplementary firearm or primary choice for deep-carry scenarios where traditional handguns are impractical.

Off-duty officers, plainclothes detectives, and armed professionals recognize this revolver as an optimal backup gun or primary carry option when traditional duty weapons are unavailable or inappropriate. Ankle holster, pocket carry, and appendix-carry setups are all viable with this platform. Federal, CCI, and other .22 Magnum manufacturers produce quality defensive loads suitable for this revolver, and the 5-round capacity satisfies most defensive scenarios where shot placement at contact-to-close range is emphasized. Law enforcement and civilian shooters benefit from NAA's track record of reliability and the inherent safety of a revolver platform—no external safeties, no magazine dependencies, and chambered rounds remain secure even under stress or during retention struggles.
