Periodically, those making their living training will either defend or castigate appendix carry. Now I don't appendix carry so I don't have a dog in that fight. It does seem to me that the issue could be put to bed with a holster that used a reverse cant - opposite of the FBI cant. That would eliminate the concern over the accidental discharge hitting an artery. Personally, I have used this cant for strong side carry (4 o' clock) for my primary since 1970. I believe it to be way faster than the FBI or straight up and down. It does take a hunt for a holster maker that will do it however. My first backup is normally in a cross draw and has been for 50 years. Controversial I know, but I have never had it snatched despite several people trying because of the retention system I require in these holsters. Have at it.
