This is not really helpful, but your question reminded me of a story.
A distant cousin of mine was a County Constable in East Texas. I saw him at a family funeral one day and noticed his duty rig was a SAA in a cross-draw holster.
I asked him, "What's the reason for the cross draw? Oh, I bet I know! It's so it doesn't interfere with the seat belt as much when you're in a patrol vehicle, right?"
He just kind of blinked at me and said "No... I just like the way it looks."
