In a semi-automatic, magazine-loaded double action firearm wherein the firing pin is cocked and released for firing by a trigger bar articulated to the trigger, a resiliently mounted arm is positioned within the frame of the weapon to intercept and eject the spent cartridge case after each firing. When the magazine is withdrawn from the weapon, the arm forces the trigger bar out of engagement with the firing pin sear, thereby preventing the inadvertent firing of a live cartridge which may have been left in the chamber.
