Having shot alot of both I can answer with "it depends", on the firearm of course. You have to ask yourself, do you have equal experience with both? A study I read says that a person with equal or no experience will always shoot a revolver more accurately than an auto. A person who has shot a revolver or an auto frequently and not had any experience with the other, will shoot better with the firearm they are used to shooting. I have been challenged before on this study, and unfortunately cannot find it, but it was in one of the more popular gun mags. I believe it to be correct, because in my experience with friends and people I have helped get in to shooting this is always the case. I love my revolvers, but a good HK, 1911, or Glock, preforms just as well in my hands for close range (under 50yds). After 50yds I have to say a revolver cannot be beat. Just my .02
