The North American Arms .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 (called Snake Shot by some manufacturers).
