Out of spec - Zaffiri Precision RTS Glock 19 Gen 3 ZPS.6 RMR Cut Slide

The front sight post hole was not centered. I used a micrometer to measure it. Its off centered by over a quarter of a milimeter. I had to dremel it to get my front sight post centered so my rear sight wasn't hanging off the side of the slide. It also does not want to eject brass properly. I swapped every part with my OEM slide and aftermarket parts. No combination seemed to make it eject properly. It works at the range while shooting, but soon as you drop the mag and try to clear it, the cartridge either jams up the slide or drops straight down through the mag well, and you drop the round. This is not ideal.
