Abstract
An improved firing safety device for handguns is disclosed. The device prevents the accidental discharge of a gun by children, but is easily removable by an adult thereby allowing the gun to be safely stored in a loaded and fully assembled condition. The gun may thus be readied for use almost immediately. The device includes a cartridge which is inserted into the firing chamber and a rod which is inserted into the gun barrel. The end of the rod is captured by and locked within the cartridge thereby preventing the gun cylinder from revolving. The device is removeable by applying manual pressure to a cap at the front of the rod which releases the capture mechanism within the cartridge and allows the rod to be withdrawn from the gun barrel.
