Mr father in law has one of a J frame that he wears almost constantly. He says he's had it "forever" which would mean he probably got it shortly after the Dinosaurs faded from their glory. While he has not claimed that he was responsible for the passing of the terrible lizards, it would not surprise me if his Clip-Draw was actually made out of dino-bone.
He doesn't seem to have any problem with it, but he is also not
what one would call "Bombastically Active."
