The only "small" gun I ever EDCed was a J-frame, and that's no longer within the bounds of what I'll carry. But I won't typically carry any "medium" or "big" revolvers either, for capacity/reloading reasons. All my semiautos are 9mm these days, and I don't go below 3.5" (never have IIRC) on the barrel or a 12 round magazine (had a few single stacks in the past), and it's been a while since I've gone below 4" on the barrel. So all in all I wouldn't say I've changed philosophy, just refined it.
