As I said, I owned an XD 9mm subcompact, and my son still has one. Outstanding gun. My only complaint was getting used to the rather spongy trigger.
Never owned an XDm, but a relative has one and occasionally has ammo issues. The XDm's have match grade barrels, which are made to tight tolerances. And his gun will occasionally have trouble chambering cheaper ammo, which is, as you might expect, not made to really tight tolerances.
