Needed an rmr slide for a 19 gen 3 - OpticsPlanet Exclusive Grey Ghost Precision GGP Glock 19 Gen 3 Slide with RMR Cut-Version 1

So I was on the fence between taking my OEM slide and sending it off to get front serrations and the RMR cut. The cost of that and the down time made me consider going aftermarket. Then this went on sale which made the decision a little easy. First this is a high quality piece. The slide accepted all OEM parts like it was machined by Glock. My RMR installed perfectly. Zero gap and a very slight amount of pressure to make it sit in place. NOTE: the tolerances are tight!!! I probably could have pressed the RMR in and shot a few rounds and it would have stayed in place without hardware. You MAY need to do some sanding/filing of your own to get your perfect RMR fit. This is something that didn't turn me off as the lockup with my RMR is ROCK SOLID. The only thing that could be more durable is if Grey Ghost built an RMR into the slide... Recoil? HA that isn't causing any hardware to walk out. I own a G45 MOS as well. Without a doubt I would buy this slide or send a non MOS slide out to get cut for the RMR over the MOS system any day! To mount the RMR I went with the water tight plate and 2 flat top countersunk 6-32 thread by 7/16 length screws. One of the screws will need to be trimmed just a touch to ensure no contact with the extractor plunger as the slide has the threads cut for the RMR above that area.
