When I first got my XD SC It had 2 Failures to feed in the first 50 rounds using WWB 165 gr FMJ. This was an OD model and I did not care for the OD Frame and the Black slide. Since I was going to send it off to Canyon Creek to have the slide refinished in Fusion OD, I decided to have Rich polish the feed ramp and do a trigger job. About a week later I got the SC back from Rich. The trigger was amazing and I really liked the OD Fusion finish on the slide. I have since put about 400 rounds of mostly WWB 165 gr FMJ (Some rounds were Remington 180 gr JHP and also some Speer 165 gr Gold Dot JHP) through the SC witout any further Problems.
