I had the same issue with my CDI kit and a 10FP. I adjusted the forward inch of the feed lips on the mag and havent had an issue since.
Jeff from CDI discussed this issue with me and it sounds as though he adjusts lips on a gun to gun basis. Its pretty common, discussed on the hide with regularity a while ago when these first came out. I would tweak the front of the mags upward and this should cure it.

ETA I just remembered the other mod I did. I also removed roughly .125 from the front\top of the mag body so the mag went in higher in the front, that cured all of my feed issues. I can post pics when I get home if your not getting it.
