Squire,
Pick up a copy of Combat Handguns and read Massad Ayoob's column. IIRC, it's called Handguns and the Law, but I could be thinking of something else.
Anyway, alot of people of various sites bash Ayoob, but IMO he give pretty decent advice in the columns. I'm not a lawyer, don't know any well enough to check with them, but what he writes makes sense to me.
