Conclusion - Grey Ghost Precision Glock Version 4 Pistol Slide w/ RMR-DP Pro Cut

I got this slide to replace my 19x which did not have an optic cut. It did favor as a good replacement. Just make sure you get the proper internals kit because not all parts were compatible. I had to use a radian tune guide rod as well which made the slide function perfectly. I have had no malfunctions with 100 rounds fired.
