A safety device for firearms, including a chamber plug portion fitting in the breech and preventing insertion of a cartridge, and an indicator located externally of the weapon and fixedly joined with the chamber plug by a connector small enough to fit within a pre-existing passageway extending between the interior of the firing chamber and the exterior of the weapon when the breech of the weapon is closed as if in readiness for firing. Preferably, the indicator is of a bright color and is located so as to be visible on both sides of the weapon.
