I have a springfield mod2 9mm and it works flawlessly... I too am looking to get a Glock 17 or a springfield xdm .45 like yours. to be honest, your's is the first of the XDm .45's that i've heard of any issues from... have you tried a lower grain projectile? sometimes going to a slightly lighter projectile can help with FTE's.... I will say that the XD's do spit casings all over the place, especially when firing rapid succession. i suspect some of it is due to the recoil/aim when rapidly firing, but i still find a casing that will occasionally fly up and back rather than to the side and back...
