Amazing slide after short break-in - Grey Ghost Precision Glock Version 4 Pistol Slide w/ RMR-DP Pro Cut

I bought this to replace my factory G19 gen 4 slide as I wanted forward serrations for press checking. The machining is precise and high quality out of the box. Tolerances are tight leading to a very positive feel while shooting. I highly recommend this slide from GGP. Inbuilt it with all factory glock internals. The first day of use was rough. Lots of failure to eject and stovepiping. I oiled and polished a few friction points after taking to GGP customer support and am pleased to report I’ve had zero malfunctions in several hundred rounds down range. My 19 never felt so good! The only thing I’d improve is the finish. It seems a bit thin as my sight pusher left a small mark on the side of the slide. Nothing major at all but a mark nonetheless. Otherwise this is a perfect replacement for OEM if you want a tight, crisp, perfectly running option that looks and feels fantastic.
