I have seen the front sight dovetail problem firsthand on a 92DXR. Also I have seen a sear installed unnecessarily in a DAO model. Also, completely absent staking on all of the grip bushings, which all unthreaded when the grip screws were removed. All of these problems on one pistol. Some of the barrels I have seen in the last few years looked like they were finished with a Dremel before the black oxide or whatever coating they use is applied. A 92 Elite slide that I have has a sight dovetail that is cut noticeably shallower than typical.
