This is what I carry around.
It's a .380, so a bit less power than you are talking about, but with hollowpoints, still effective.
It's small, very lightweight, and fits in your pocket with ease. The integral laser is a nice thing too. I think most people have been conditioned by hollywood to fear having a red laser on them. so it adds a bit of psychological intimidation as well. the one time I ever had to point it at someone (Meth head crashed a jeep into my garage and was all crazy about it) the guy didn't react to the gun pointed at him, but ran when I turned the laser on.
My take on a carry pistol is it to place a priority on ease of carry and unobtrusiveness. Having a more powerful, accurate weapon is great and all until you don't bring it with you because it's a pain in the ass. this thing you can have on you wearing just shorts and a t shirt and no one would know. 6 in the clip is enough to dissuade some one from having violent intentions towards me while I execute my exit strategy. I carry it safety off, with no round in the chamber. It's safe enough for me that way. the amount of time it takes to chamber a round is negligible as far as I'm concerned.
the only issue I've had with it was the plastic inside the belt holster I got for it would squeeze the mag release. Once I figured out the issue I modded the holster and its fine now.
I've had no malfunctions at the range with it.
