A non-lethal, legal weapon is always the best option for self-defense. Even if you are carrying a lethal defense weapon, such as a gun, is lawful after you obtain a license to use it. But you can't use it unnecessarily. Therefore, pepper spray, a stun gun, or a taser are the best self-defense options.
Stun guns are extremely potent in high-stress scenarios, such as high-risk warrants, riots, active shooters, and other dangerous situations. It's a self-defense device that you can use to stop someone from attacking you. It uses high-voltage energy to immobilize the attacker instantly.
It is designed to transport the energy into a person's muscles at a high pulse rate, causing the muscles to function at a very fast pace but in an inefficient manner. This makes it hard for the attacker to move or attack in any way. For a short while, the attacker will be puzzled and confused, but no harm will be done to his essential organs.
When to use a Stun Gun?
A stun gun should only be used in self-defense situations, where you have no other way to defend yourself from an attacker.
Of course, if at all possible, you should stay away from potentially risky situations. However, if you are going into a dangerous place, you'll need to take precautions. And if you are approached by an assailant and feel unable to protect yourself, this would be the best opportunity to use a stun gun in self-defense.
