Zap&';s Blast Knuckle Stun Gun is a uniquely designed stun device to take advantage of the way we use our hands. You only need to touch your target with these knuckles to deliver a 950,000-volt blow that will cause further disorientation and may drop them to their knees. It is rubber-coated with a soft contour grip for full control and has a red LED on/off indicator. It includes a heavy nylon case with a belt clip and 2 CR123A batteries.
