"Are we really implying that "most" are not prepared for a "fight"?"
I'm not at all sure where, why, or how you're coming to that conclusion. The simple fact is that very few people are ever truly prepared for potentially deadly encounters in which they find themselves. That's just one of those things, and part of it can be making the best of the situation with what you've got.
Obviously my comments about "knowing if I'm going into a social situation, I'll pick XXX" fall into a category of exceptionally unlikely to ain't never, ever gonna happen.
"Discounting all those real world CCW folks, is a fight then only in theory, wherein we can fantasize about what gun we brought to the fight?"
Fantasizing would be imagining you're Roland Deschaine and on a quest to the Dark Tower with your trusty gunslinger iron on your hip (I can't wait for this movie to hit the theaters!!!)
What we are doing here, or at least SHOULD be doing here, is discussing the guns and their capabilities first and foremost.
That said, I think most CCW people, myself included, carry revolvers that aren't fighting revolvers, they're the small defensive revolvers -- J Frames -- that I talked about earlier.
If I were ever to get into an encounter where I needed a gun outside my home, I'd almost certainly do so with what I term a defensive revolver, not a fighting revolver.
