It was an actual ring the Officer or whoever, would wear on their finger and when the gun was pointed away from the Officer ,at a perp or the like, the gun would fire. If the perp somehow got a hold of the officers gun and the gun was pointing at the officer ,and the ring, the gun would, not fire making the gun useless even if the perp got away with the gun.
