Stun Guns With Disable Pins or Kill Switch.
The following stun guns all have one thing in common, they have the pin on a wrist strap that needs to be in place in order for the stun gun to work. So if you have the strap on your wrist when you are threatened and by chance have the stun gun knocked away from you, you will be OK, because the stun gun will not work without it. The assailant cannot use your stun gun against you.
