Can't carry here (yet, may change in the next two months), but if it were legal I think I'd keep the chamber empty. Most of the mechanical things I've operated over the years have screwed up one time or another (or, to be fair, maybe I screwed some of them up, but that distinction doesn't matter here). Compared to not being able to carry at all, the extra half-second it takes to work the slide seems like seems like a minor price to pay for the extra margin of safety. If it were a higher threat level situation, my opinion would change. But for a trip to McDonald's with my kids? Nope.
