To each his own. I have no issue with concealed carry per se. Having gotten this far and never having encountered any scenario that would even vaguely require one, I can't see starting now. Maybe I project a "don't fuck with me vibe," maybe I've just been lucky. Maybe when I'm 70 and looking a little more frail I'll think differently. I definitely can see the value for women to be armed, if they know how to use it. For now, my ranking of threats to my person tells me that daily carry would be more trouble than it's worth for me.
As a non-carrying person, I don't have much of a dog in this fight. To the OP, though, I side with some of the earlier posters. Capacity shouldn't matter too much. If you're getting into a protracted gun battle with someone, things have spiraled wildly out of control. The primary goal is deterrence. Once that's failed, it's self-defense. If that takes more than 6 shots, you're dealing with someone who didn't want to just rob/rape/assault you, that person is trying to kill you, specifically, for a reason. If you're someone who thinks there is actually a hit out on him, you're either one, insane, or two, an actual target, who needs a full personal security plan from top-to-bottom, not just a piece.
