I have only had this XD-40 SC for a couple of months and I am still evaluating it for carry. During the first 50 rounds it had 2 failures to feed. The feed ramp was polished and I now have about 400 rounds through it without any more problems. I recently got it back from Canyon Creek where the slide was refinshed with OD Fusion color and a trigger job by Rich. Most of the ammo ran through it was WWB 165 gr FMJ and also some Winchester Ranger 165 gr SXT (Talon).
