I took my original extractor and polished most of the casting marks off the top and bottom. I used a arkansas stone to do this. I left the new 30274 ejector in the gun. Went to the range today. Ran 50 rds, I had 7 come back and hit me in the head. About half went to the 4 O'clock. The rest went straight up.
So polishing the extractor has made a big difference. I'm calling this promising.
Time to get the files out.
