I was traveling with my firearm in the approved case within a checked bag, and one zealous TSO decided that merited some extra inspection of my bag. Okay with me, check away. He decided to have me open the locked gun case, whereupon he swabbed the revolver itself and put the pad into the scanner. He seemed alarmed when he told me it was positive for explosive residue. I replied, "It's a gun. What did you expect?" He called his supervisor, who told him to lock up the case and send it through.
