Never had trouble with an xd. However, I'd go with a single stack for cc.
I have a compact single 1911 .45. I should've said for carrying, not necessarily 'concealed'. I carry OWB w/a shirt hanging over it but no longer concerned if my shirt rides a little high or if it becomes unconcealed. I carried a G23 this way & it's a bit bigger than the Mod2 sub-compact.
I can't believe I haven't got more hits on this thread. Is this not a very popular gun?
