I had absolutely no problems at Gatwick whatsover other than the security office kept telling me that "special handlers" would be bringing my guncase up from baggage for customs inspection. I stood around for half an hour waiting then finally wandered over only to find it going round and round on the belt.
I carried it back to the security office and they were much surprised. The man walked me over to customs and actually lied to the customs official telling him that the "special handlers" had brought it up. He winked at me as he turned around away from the desk and I never said a word of course.
