You need to have some level between "make the drunk stop harassing that lady" and "put a bullet in him". You are right, threating with a gun may lead to the second option, which is why I would never even present a firearm into the equation. Just because you have a firearm doesn't mean you have to use it. Why not carry both, it isn't like it is either/or.
Although, I wish the legislature would remove ALL restrictions on all items. It isn't prohibition anymore, who gives a crap about the size of an OC can that my wife wants to carry. Thats my 0.02.
