I'd probably get another "old school" Springfield XD-9 sub-compact. Not the -M, not the -S. Just the plain "classic" XD. Why? Because they're ergonomically friendly to my hands, conceal well and comfortably, and I already have one, and my wife has one. Stick with what you know, right?
When I CC in PA, I use my XD-9 sub-compact, and carry a 16-round spare mag.
