Major quality and spec issues - Grey Ghost Precision Glock Version 4 Pistol Slide w/ RMR-DP Pro Cut

The looks of this slide are fantastic but the functionality is horrible. First is that I bought it to go on a Grey Ghost Precision Frame and it did not perform at all. it jams ever round (150 rounds shot so far) cause of the slide rail slots are to tight on the frame rails and when being inspected by a gun smith there was a bur on the inside of the safety plunger channel which was diamond filed down then used again and still was jamming. Lesson learned and will go with reputable companies on builds.
