“If someone is uncomfortable with carrying one in the pipe then they probably shouldn’t even bother carrying a pistol”
Thats rather presumptuous of you. Some people prefer it that way and they as much or more knowledgeable than you appear to be.
If it's a preference to carry with an empty chamber then it's a preference made without being knowledgeable on the subject. The only reason to carry a pistol is for protection and it isn't going to protect you if it doesn't go bang when you pull the trigger. Racking a round at the last second might make for more drama in a movie, but no professional is going to do that in real life.
It's not clear to me from your post what you mean? Are you advocating keeping the hammer down on an empty chamber of a revolvers cylinder or, not chambering a round in a semiauto until you need to use it?
