There are a lot of comments out there as to whether a stun gun is effective. And, as most people do, I have an opinion.
First, I think we have to identify what stun gun is designed to do, because many people think they’re supposed to instantly cause someone to fall down and have them quiver on the ground uncontrollably. And, while this might actually happen, its not what a real stun gun is designed to do.
A stun gun is designed to at first, look menacing as hell to hopefully prevent someone from coming forward towards the victim. And, unfortunately, there are many crappy quality stun guns out there that don’t put off enough of a spark to make anyone really care that you have it in your hands. Second, these weapons, if used, are designed after several seconds of contact, not instantly (note I said after several seconds), to repel an attacker. They may or may not fall to the ground. But, if the weapon has enough amperage, it will cause whomever is receiving the jolt to back off. And, this is what a stun gun is designed to do. And, third, once again, if its used for several seconds on an attacker and it has enough amperage, the attacker will most likely be disoriented enough to not be able to move forward. Potentially, they may fall to the ground. But, at least they’re “stunned” enough to give the victim time to get away.
And, this is what a stun gun is designed to do. But, notice also, that I said that the weapons need to have enough amperage. So, what is enough amperage? Well, 5 milliamps is considered lethal (deadly). Most cheap chinese stun guns generate a whole 1 milliamp or so. This is negligible when it comes to stopping someone. Most average to good units will deliver about 3 milliamps and this is effective if they are applied for 4-5 seconds to the average human. The highest amperage stun gun is the Barracuda BC37 and BC10 which deliver 4.5 milliamps (just under that 5 milliamp mark) and they will deliver the “stun” when applied for 2-3 seconds onto the average human.
So, again, its important to know what a stun gun is designed to do and what makes an effective stun gun. Just like anything else in life, when you buy a cheap piece of crap, you get crappy results. But, when you buy good quality, you get good results.
