After just purchasing an XDM 40 and shooting 250 rounds of ammo including WWB ,Blazer Brass, powerball, and Cor-Bon using three different mags I experienced over a dozen rounds that failed to feed. I am not a gunsmith by any stretch. but it looks to be a faulty ejector that is binding on the shell casing as it is being pushed upward into the chamber. While clearing the failure to feed rounds I also discovered the mag release to be extremely stiff when mags are near full capacity. While lurking this forum I see that these problems have happened to others and they have been corrected by Springfield. I just sent the gun to IL this A.M., so far springfield cust. service has been excellent. Its just a little disappointing having to send a gun off for service 2 days after the purchase, not to mention the 100% reliability/ piece of mind factor. Anyway wish me luck.
