I always have a loaded firearm in the glove box along with my wallet and ccw. When, not if, I'm stopped
I have both hands on the wheel and inform the officer all my id is in the glovebox with a loaded handgun. Reactions have ranged from "reach over and grab your wallet" to the officer going over to the other side and opening the glovebox themselves. Once I had a youngn' looking straight from the hitler youth ask why I had "so many" guns.(My primary and secondary, which I forgot to hide) I said, "they're like potato chips, can't have just one." Got a confused look in return and he left.
Never was really concerned about the officer "taking" my firearm. I always have a second one, (tinfoil hat on) just in case.Classic
