Purchased the Zaffiri Slide / Upper Parts Kit, Trijicon HD Night Sights (Orange Front Outline, Glock 42, 43 GL113-C-600785), and the Holosun EPS Carry–GR-MRS to upgrade my Glock 43. I also installed a new Brownell barrel that I had previously bought. The parts looked flawless with no marring or scratches. Assembly went smoothly with the exception of installing the Trijicon rear sight. The sight would only fit into the slide cut about 1/8th inch until coming to a dead stop (I used a nylon tipped punch with the slide in a vice for the initial installation). I could see the finish of the slide dovetail peeling up as the sight was being inserted. I attempted to install the sight from the opposite side with the same results. Either the slide was cut to small, the sight dovetail machined to big or the Cerakote coating on the slide applied to thick. I used a small triangle file to remove the high spots each time I attempted to install the sight. Since the sight overlaps the slide at the back with little clearance you need to be careful not to remove too much material. Finally after getting the sight about 1/3rd of the way installed a sight press was used to complete the installation. Unless you have experience I would recommend you take the parts to a gunsmith to have this work done instead of removing too much material from the slide or sight. While having interference is not a common issue it does happen. The night sights co-witness at the bottom of the red dot sight window leavin
