The only reason I would be racking my shotgun is to put a round up in the chamber. If racking my shotgun makes a intruder leave then so be it. I would not want to be at home with a unloaded
shotgun and a intruder who did not leave at the sound of my racking gun. Any intruder who does not leave when I put a round in the chamber of my shotgun will be going to meet the Creator for Judgement Day!
I do not keep a round in the chamber of my shotgun, but my 9MM has one in the pipe and ten in the clip at all times. ( I have two extra clips full and ready)
