I fly with my handgun pretty often. Almost never a problem (my line at the counter is to smile and softly say to the clerk, "I'd like to declare an UNLOADED handgun."). Anyway, flying out of San Diego one time the clerk had me leave the gun container unlocked for checking with TSA. Luggage disappeared down the moving conveyer belt. Next time I saw my luggage was in Boston. All was OK but the damn gun bag was STILL UNLOCKED!!
