Anyway, there are a number of things that can go wrong with this. The big one being is what if you grab your gun and in the heat of the moment you forget you have a safety bullet in and pull the trigger? Or someone else pulls the trigger just messing around (say a kid gets a hold of it, which is a possibility otherwise you wouldn't be considering this) and you don't know? Not only does nothing happen when you try to shoot the bad guy, your gun is disabled and you and your family are dead. Keeping an empty chamber isn't a great alternative, but it's miles better than this gimmick.
