North American Arms 22MCP Mini-Revolver 22 LR/22 WMR 5 Shot 1.63″ Stainless Steel Ported Barrel & Frame, Stainless Cylinder, Rosewood Birdshead Grip, Exposed Hammer, Includes 22 LR Cylinder

NAA’s .22 Magnum Ported mini-revolver is the ultimate in up front, personal, close-in protection. It’s small, easy to conceal and safe to carry, using the half-way notch cylinder so the hammer may rest safely and securely away from live or empty chambers without chance of accidental discharge. The 22 Mag cylinder can be used with all popular .22 Magnum ammunition, including .22 Magnum shot-shells. This model has a ported barrel and comes with a special .22 LR conversion cylinder made longer to easily fit in the .22 Magnum mini-revolver.
