I have a 10mm in wonder finish. It is my daily carry.
I had a few ftf's in the first 300 rounds. I upgraded the recoil spring to a 22lb (mainly to prevent battering of the frame with true full-tilt 10mm ammo), I buffed the feed ramp with my dremel with the felt tip and some buffing compound, and I upgraded the mag springs to wolff +15. This was all done during a three week period in which I shot the 300 rounds, in 50-100 round sessions.
Since that time, I have another 1500 rounds throught he gun, and have had 100% reliability.
