The Double Trouble Stun Gun is more effective than most stun guns because of the space between the contacts! The greater the space, the greater the effect! Most stun guns only have 1.5 inches, while the Double Trouble Stun Gun has 5 inches between contacts! This stun gun is like having 2 stun guns in one, with twice the contact area and 1.2 million volts of pure stopping power. Our tough durable Double Trouble 1.2 Million Volt Stun Gun is built with a soft countour grip that is rubber coated for maximun handling grip, and comes with a safety switch that provides an LED light letting you know the gun is on and ready to fire.
