"Revolvers will get you killed" is an absolute statement. When SHTF, and things go wrong, nothing is absolute. It doesn't matter if the sample size is 1 or a million - each situation is unique, with thousands of possible outcomes. You can't plan for, or anticipate all of them, and carrying more ammo doesn't necessarily make you more ready or prepared. Besides, its just as easy to carry extra speed loaders for a revolver, as it is to carry extra mags for an autoloader. Furthermore, there are a lot of compact autoloaders on the market that don't hold many more rounds than a revolver. Are those gonna get you killed as well? On the flip side, having less ammo is not gonna magically make you more accurate. By that math, we should all be carrying a single-shot. I still say carry what you're comfortable with. Being ready and proficient with your firearm of choice is far more important than how much ammo you're holding.

PS. When I read the OP, I assumed we were all talking in terms of concealed carry firearm choices, because that's really the only situation where you're limited in what you can carry. Now that I've noticed some are talking about home defense, I do have something to add. In your own home, it doesn't really matter if you start out with an autoloader or a revolver. If you don't have an AR, or a 12 gauge shotgun, or a whole bunch of extra ammo strategically located somewhere you can get to easily, I would probably question your life choices.
