The NAA-22MS is built on the magnum-size NAA Mini-Revolver frame and is chambered in .22 WMR. It operates in single-action only with an exposed spur hammer and a spur trigger, and it omits a trigger guard by design. The 5-shot fluted cylinder is removable via a knurled, spring-latched base pin for straightforward unloading.
Construction is all stainless steel, including the frame, barrel, and cylinder, with a matte stainless finish throughout. Two-piece hardwood birdshead grips provide a compact, traditional profile that complements the revolver’s micro dimensions.
Dimensions are notably small: overall length is 4.63 inches, height is 2.81 inches, and unloaded weight is only 6.2 ounces. The barrel measures 1-1/8 inches. Fixed sights comprise a half-moon front and a fixed rear notch, providing a simple, durable sight picture.
Manufactured in the United States, this example delivers the hallmark NAA mini-revolver design in a durable stainless-steel package, with the included NAA-branded suede pocket holster and a zippered soft rug to round out the set.
