This Companion model uses cap-and-ball percussion ignition with #11 caps and a 5-shot unfluted cylinder. It operates single-action only with an exposed hammer and a spur trigger, providing simple, consistent function in a compact package.
The barrel is 17-4 stainless steel with an integral rib, matched to a stainless frame, cylinder, and receiver finished in matte/brushed stainless. The fixed half-moon front sight complements the minimalist profile; there is no rear sight.
Factory dimensions are micro-sized at 4.0 inches overall and 5 oz, with a 1.13-inch factory barrel length. The smooth laminated rosewood birdshead grips offer a classic look while maintaining a compact footprint.
Loading is performed with an external tool, as there is no attached loading lever. A knurled base pin under the muzzle aids disassembly and maintenance. The frame carries the model roll-mark “Companion,” and the manufacturer part number is NAA-22LR-CB.
