no, that is hollywood nonsense, people don't grab guns out of each others hands lol, it is far more likely that someone would grab or wrestle a knife out of your hand. Self defense is a constituionally protect act, there is no state that can try you if you have a legally owned firearm and use it to protect yourself from harm. Of course, if you are ina state that doesn't allow hand guns, which off the top of my head , I don't know which ones that is,it would be a major problem.. I know that here In IL , we can conceal carry with proper identification.
