“A one second test sends out a menacing display of sparks and a loud ZZZZAP. Just firing a test burst is often enough to get an assailant to change their minds.”
Yes, unless your assailant has a gun...or thinks your
Taser would be a nice toy for him to take from you and have for his own...or both.
If that were the case, then he would have made my stun gun a moot point, and I would pull my Glock 40 S&W. This isn't for those kind of situations.
Somebody threatens you with a gun, deadly force is legal where I live. The stun gun is for situations where the threat doesn't rise to the level of deadly force. Think of some drunk with a chip on his shoulder who doesn't care whether or not you want to fight.
