None at all, which is why I focus on KISS; two rounds in center mass, seven yards or less, starting from a low ready.
I do recall an article prob’ly more’n thirty years in a Guns Annual by one Wilfrid Ward on British military revolvers. In it he mentioned that to pass their 1920’s era Revolver School, starting from a one hand low-ready position you had one second to put a round into a 10” x 15” target. I forget the range, I’m thinking thirty feet.
Eminently practical. Seems like the Brits were way ahead of us from the Nineteenth Century into the 20th when it came to combat handgun training.
