"If you disregard operator induced failures.(Such as bumping slide lock), magazine failures on new unproven magazines, and ammo failures (such as out of dimension or failure to fire) I've seen zero failures in the last 6,000 rounds."
That's the problem. The failures weren't the pistol's fault, but they were still failures.
On a typical range session my FiL and I shoot about 600 rounds total, about 300 through semiautomatic pistols and about 300 through revolvers. It's typical for us to have at least one failure with the semiautos. It's very rare for us to have a revolver failure. Sure, we bring good semiautomatic pistols and the failures "aren't their fault'. One of us limp-wristed it, or there was a bad primer, or the cartridge was slightly misshapen so that it fit in the magazine but not in the chamber, or we bumped the slide or engaged the safety or whatever. Admittedly, some are failures of 22lr's and some are failures of reloads where the cartridge is stretched a bit funny or something.
Still, it makes me feel more comfortable with a revolver for CC. If someone jumps out of a bush and grabs you around the throat because they want your keys and wallet, you will not be able to clear a problem. Your handgun will either discharge immediately and properly, or you will be done for. I do carry semiautos sometimes, but revolvers make me feel more comfortable.
