Another vote here for the XDs. My decision when I was searching for a sub-compact was that it should be a single stack. Something like a Glock 26/27/30,M&Pc/XDsc, etc didn't necessarily give me any more concealment advantage over a compact/FS pistol (like my XD9), due to the thickness. Given that fact, I feel that if I'm giving up capacity by going single stack, it ought to be balanced with a larger round (JMO, YMMV).
Also, very nice pic, uudl. I'm curious, who makes your holster? That's precisely the IWB I'm looking for (offset clip, not low riding, leather).
