I'll still disagree with your theory. Regardless of how fast a shooter may cycle their action if it takes them the same amount of time to aquire a good sight picture, for them, and break the shot they have gained nothing. It takes them the same amount of time to run a stage. Just because they have the tools doesn't mean they'll be any faster, yes the potential is increased. However, some shooter will never move any faster. Give them the best holsters made and if they still use both hands to pull their pistols and holster they're merely looking better doing it. Guess I'm just saying the better shooters have the most to gain by SS'ing guns and the others have little to nothing to gain unless they can break bad habits and smooth up their shooting skills.
FYI, my Corvette guns are misfiring and are only running on 4 cylinders.
