In order to answer this question, we must first define what a stun gun is supposed to do. So many people think that a stun gun is supposed to instantly drop someone to the ground and leave them unable to get up with just an instant of contact. This is simply not the case. Anything that acted this quickly, would most certainly kill.
So, what is a stun gun supposed to do? Well, first, a stun gun is designed to instill fear into someone who sees you have one. Preventing an attack is much better than winning an attack. And, think of this: Do you like to be shocked? Do you even like the little bursts of static electricity shocks that happen throughout the course of a day? Do you like the shock of a 9v battery on your tongue? I can’t say that I’ve ever met anyone who LIKES the feeling. And, knowing that a good quality stun gun generates SUBSTANTIALLY more electricity than static electricity or that of a 9v battery, most people, upon seeing a stun gun being test fired into the air will not want to come into contact with it. So, if that alone scares off an attacker, the stun gun has worked.
Secondly, a stun gun is designed to cause severe discomfort, mental instability, and yes, possibly, causing a person to be physically disabled to the point of falling to the ground, when actually applied to the person. But, does all this happen with just an instant of contact? No. The amount of amperage determines how long a stun gun has to be applied to cause these effects. Most good quality stun guns generate about 3 milliamps of electrical current. (notice we’re talking amperage here and not voltage….voltage is an entirely different subject and does not determine how effective a stun gun is). And, 3 milliamps of current will generally take between 3-5 seconds of direct contact to cause these effects to occur. The highest stun gun out there, the Barracuda BC37, generates 4.5 milliamps of electrical current, while 5 milliamps is considered lethal, or deadly. So, 4.5 milliamps is right below the threshold of what will kill someone. And, at this level of electrical current, generally 1-3 seconds of direct contact is required to cause these effects.
Now, will all that said, there are many, many, many cheap stun guns on the market that will not really do anything more than that 9v battery on the tongue kind of thing. So, you do have to make sure you’re dealing with a high quality stun gun to begin with. And, even at that, just as some people can take a bullet and still move forward, there are some people who can take a shock and still move forward. So, there is virtually no self defense weapon that works on 100% of the people, 100% of the time.
And, so, if you have a high quality stun gun that can prevent an attack and/or that can cause most people enough severe pain and mental instability, then, yes, you have a stun gun that works. If you have a cheap stun gun, then, no, it probably won’t work.
