I don't think it will change at the top of the sport. Most of those guys are running 5" edge style pistols. It's mainly because that's what they've always shot. It's that whole Indian, arrow thing. I shoot a 6" because I like it and I think they are cool. I do t think it gives me a real measurable advantage but if it makes you more confident then that works too. Shoot what you want, just put in the time.
