I shoot either type of handgun well; so accuracy or ease-of-use aren't issues. My preference is for revolvers; I own a few beauties; and I enjoy showing them off, too.
(Somehow a nice revolver is just classier and more traditional looking. The other thing I like about revolvers is that - unlike the flat panels on a semi-auto - the frame can be fitted with a beautiful, oversized, custom wood or horn grip; and, that's something I've always particularly cared for.)
All this said, what I carry all day long and for almost everyday of the week is a big fat ugly Glock Model G-21. Why do I do this? In a word: 'Firepower!' We are presently living in what is, perhaps, the meanest, dirtiest, and most violent social structure the world has ever known.
These vicious realities require me to take the possibility of a violent assault by multiple gang members very seriously. I want to know that, in addition to knowing how to use a handgun well, I also have the ability to successfully engage several opponents simultaneously.
So, whether it's for multiple assailants, a prolonged engagement, or having to turn my carry piece over to a police investigator - in the full knowledge that it's going to be tagged and dumped into an unkempt evidence locker - for everyday street carry a relatively cheap, plastic, high capacity, semiautomatic pistol just makes more sense.
I carry an extra magazine with mine. I only have to reload once instead of three times; and I'm, 'good to go' with 30 rounds of ammo should the occasion ever arise. If I ever have to turn this Glock over as evidence, who cares! (It ain't like it's a custom-built S&W Model 626 with a glass-beaded action job and an exotic wood Hogue Monogrip.)
In today's increasing violent world a semiautomatic just makes more sense.
