The North American Arms 22MP: This is a .22 Magnum Ported mini-revolver from North American Arms that\'s designed to provide the highest level of protection in close-in, personal confrontations. Its compact size makes it easy to conceal and ensures that it\'s safe for carrying. The feature of the half-way notch cylinder allows the hammer to sit safely, reducing the risk of accidental discharge, whether the chamber is loaded or not. What sets the 22 mag cylinder apart is its compatibility with all popular .22 Magnum ammunition types, including .22 Magnum shotshells - also referred to as Snake Shot by some manufacturers.
