As I and others have said, there are many "virtues" of a revolver. I prefer one, except for defensive carry. For some people, and in some circumstances, revolvers are the most practical choice for self defense. But realistically, the semi-auto is usually the better choice for that purpose.
I happen to agree, and I chose to wear a 6-shot 357 today.
When discussing carry pistols, an instructor gave me a hypothetical once: assume you know with certainty that you
will be forced to use lethal force this week to defend your life and the life of your loved ones. You don't know when, who, where, how, or how many - you just know that it
will happen. And your daily routine must continue - you can't just stay home or go on vacation. Given that, what will you carry this week?
My answer was (and is still) a steel framed 1911 because I shoot those the fastest, with good practical accuracy, and I can reload them quickly and without thought. I'd choose the most effective caliber I own as well, because I'm wired to think size matters. So gimme a steel commander in 45ACP with 2 spare mags as I typically carry and I'm good. I could just as easily grab a double-stack as well should I feel like capacity was more important than projectile diameter, but 1911-pattern it is, in a mostly full-sized platform.
Now, shooting a revolver is more pleasant, and I can make long distance and precise shots more consistently with a revolver, and the 357 is nothing to sneeze at. If I expected my wife to need to step up I'd likely give her a revolver, as she grew up shooting a Python. But if her life is on the line, I'd prefer more than 6-7 shots to resolve the problem.
But there's a reason most folks who expect to have to do serious social shooting choose a pistol over a revolver. And maybe I'm a bit Fudd-ish by not just grabbing a Glock 19X which is way cheaper than what I carry, plenty reliable, easy enough to shoot, and 9mm is likely "good enough," but I like what I like and luckily I can indulge a bit on the arms I carry.
Revolvers have some great advantages - again, I've got one on my hip right now (a pretty, lightweight blued beauty) - but for combat use you give up a lot.
