A stun gun is a defensive personal protection device which makes direct contact with the attacker. It can disable an opponent using an electrical shock but will not cause critical injury. The weapon is different from a taser which shoots at a range of 15 feet to 30 feet. A stun gun possesses prongs mounted on it that emit the electric shock. A stun gun is a highly effective personal protection weapon. It works even if your opponent wears thick clothes. Pressing the switch of a stun gun delivers a cracking electrical sound that is more than enough to scare any attacker and change its mind attacking you. Each state features its own stun gun laws. It’s important to understand the laws of your state before you make an attempt to buy one.
