I'd rather just carry my 14 ounce, 11 shot, smaller than J frame sized Kel Tec P11. I mean, that's what the 9 was designed for. I really never quite understood the 9mm revolver thing. I guess if you're die hard for revolvers, the 9 does make sense as a caliber. it's very efficient, gets up close to .357 magnum in energies from a snubby, yet doesn't have all the flash/bang of a .357. I can take or leave the moon clip thing, personally, but some prefer it for its speed. To me, that's tempered by the fact that reloads are all or nothing. Speed strips can top off.
Like anything else, there are trade offs, I guess. Just gotta weigh what's important to you. For me, though, the little P11 is all the 9mm revolver I need, personally. It's very accurate, very reliable, and very concealable.
