I have an XDM. Its nice having that many rounds (13 45acp) "on hand", however, there's something to be said for the double stack 45 grip. I have big hands and still have a hard time getting a good, vicelike grip, like I can get with a 1911 or my P345 (single stacks). The gun is pretty accruate; it's no Les Baer at 50 yards, but it groups in in the 7 ring. Strangely, the XDM 45 and Ruger P345 use *exactly* the same holser.
