I've got some experience with the XD9. I'd like to hear some experiences of the XDm, 4.5...in any regard. Ergonomics, fit, finish, recoil..muzzle flip...etc. How is the XDm different for you? Any comments? I like the XD fine....but I like that the Glock 17 is a little larger for an HD gun...so naturally I'd float towards the 4.5 XDm since it's roughly the same size as a Glock 17....any comparisons there?
