I have experienced that the EMP runs best when wet. I used grease as a lapping compound when I first got the gun. I experienced my first FTF on the 600ish consecutive round on the first day. The feed ramp was filthy. Since then, I have not shot more than 600 in the same day, and I have not had another FTF. Keep it clean and wet. I have a 4lb trigger job and it's just right for a CCW gun. I take it everywhere.
