I do find it reassuring to hear what you say about "there isn't a holster on this planet that makes the G26 any skinnier". That's what I keep thinking, but I'm so surprised that I don't see that more often in replies. As I said before, even just carrying the 19 without a holster (which makes it even skinnier than if I carry using a good holster), it's still not comfortable.
I guess we all have different comfort requirements, but I'm willing to give up a little comfort for a gun with great capacity, and a more robust design. To me that's comforting.
OWB is a comfortable option, as long as your shirts are long enough.
