The North American Arms 22S is a mini-revolver chambered in .22 Short, a rimfire cartridge known for its low recoil and relatively quiet report compared to other handgun cartridges. The 22S typically features a short barrel, usually around 1 inch in length, contributing to its ultra-compact size. Despite its diminutive size, the 22S maintains a five-round cylinder capacity, allowing for multiple shots before reloading. These mini-revolvers are constructed from stainless steel for durability and resistance to corrosion. The fixed sights on the 22S typically consist of a notch rear sight and a blade front sight, suitable for short-range engagements. NAA mini-revolvers, including the 22S, operate on a single-action mechanism, requiring manual cocking of the hammer before each shot. Overall, the North American Arms 22S offers shooters a compact and reliable option.
