I'd go for the SubCompact w/3" barrel...Easier to CC and a bit lighter but PLENTY enough gun for off-duty... I find myself appreciating "smaller and lighter" more as the years unfold. But it would mean going to .40 (or 9mm) so you may not be into it. I'm just sayin'... the .45 "Compact" isn't really very compact.
PS: If you want to stick with .45 in light and concealable... If you're willing to go single-stack, any of the Kahrs are sturdy and reliable and come in various sizes... I have CW45 and CW9 (they're great). Double-stack... the Para-Ordinance Warthog is worth a look at 24 oz. 10+1.
