Yes this slide is cut for RMR and DP pro footprint optics, and since the 507c is an RMR footprint it will work on our slides with the included RMR shim. Just make sure you are using 6-32 thread pitch screws and that the RH screw is not too long - if it is, it'll impinge the extractor depressor plunger and give constant failures. Thanks!
The Grey Ghost Precision Glock Version 1 Pistol Slide w/ RMR-DP Pro Cut includes shim plates used for when you want to install either a RMR style optic, or DeltaPoint Pro (DPP) style optic. Since the optic cut is designed for two different footprints, you must use the correct shim (included) to install an RMR. It also includes a G10 cover plate and proper screws for cover plate, and correct length screws for RMR and DPP.
This Grey Ghost Precision Glock Version 1 Pistol Slide has a slide cut for a Trijicon RMR which uses a different footprint than the Vortex Venom. There is not a mounting plate that will allow you to mount a Vortex Venom to this slide. You would need to get a slide for your specific gun that has a slide cut for the Vortex Venom.
No, it will not fit the Romeo1. Only our our Sig compatible slides are designed to accomodate the Sig optics.
