A local guy has this gun for sale, and trying to pay a fair price. It comes with 8 tuned MBX mags. Any guidance would be much appreciated. He is wanting $6k.

Got to be the sear spacer or sear adjustmentin my opinion. I had the exact same specs, and eliminated those two and works perfectly. Trigger screws shouldn’t be all the way in or out.
Try adjusting the pre and overtravel screws in trigger. Adjust and put slide on, test, retest and blue locktite. Hope this helps. Had the same issue.
Could also be the disco or sear spacer. Had the hand fit and went back to the oem. No issues now
I changed/added - CGW floating trigger pin, while you are in there the CGW reduced trigger return spring. There are good videos out there showing full breakdown.
