^^He tried the extractor too. Another factory extractor, a LWD 9mm LCI extractor, the 0-4-2 guide rod, hot ammo, higher grain ammo, different magazines, a different factory extractor depressor plunger assembly, a White Sound Defense HRED EDP assembly, and reprofiling ejectors a couple of different ways. AND all of those things in every combination he could think of. With all the effort he's put into getting it running right he probably could've just bought another gun.
He had a little more success with one of the reprofiled ejectors, but was still getting some brass to the face.
