My point is and I believe it could be backed up by most shooters is simple.
Who gets the most hits on target in the least amount of time when shooting more than 5-6 rounds.
I see what you're saying, but I think the reliability of the revolver trumps the capacity of the auto.
The bad thing about the auto is that an otherwise perfectly functioning auto can fail to feed or fail to eject for no good reason, at any given shot.
I've seen it happen way too many times to feel comfortable carrying an auto for self defense.
So, you might have 15+ rounds in your auto, but one failure-to-feed or one failure-to-eject, or a stovepipe, or a dud round, or a hard primer and you might suddenly have a one-shot handgun.
And unless you practice stoppage drills religiously and frequently, you're probably better served with a revolver.
And I can honestly say that I never see folks at the range perform a stoppage drill when they encounter a failure.
It's always Bang! Bang! "nothing"....and they guy stands there and squeezes the trigger again, looks at the pistol in a puzzled manner, slowly removes the magazine, etc....
I never see anyone instinctively and immediate perform a stoppage drill.
If they don't do it instinctively at the range when their weapon fails, they will not do it instinctively in a real life shooting under duress.
Yes, I know that revolvers can jam too.
But not near as often as autoloaders do.
And the vast majority of revolver jams occur when or immediately after reloading.
With a well maintained revolver you are practically guaranteed the first six shots.
With an autoloader, which has a round in the chamber, you are only practically guaranteed one shot.
