The PMR-30 is a light weight, full sized, pistol chambered for the flat shooting 22 magnum cartridge (.22WMR). It operates on a unique hybrid blow-back/locked-breech system allowing use of a wide variety of ammunition as it seamlessly adjusts between locked-breech and blow-back operation, depending on the pressure of the cartridge. The double-stack magazine holds 30 rounds and fits completely inside the grip. The crisp, single action trigger has an over-travel stop, the manual safety is a thumb activated ambidextrous lever, and the slide locks back after the last shot. The light, crisp trigger pull and fiber optic sights make this pistol ideal for target shooting and small game.
