A safety device is provided for a handgun having a trigger, a hammer and a trigger guard. The safety device contains a hammer locking end for locking the hammer, a trigger locking end for locking the trigger, and a structural support member extending between the hammer locking end and the trigger locking end. The safety device thus locks both the trigger and the hammer and is releasably connected to the handgun.
