The Zaffiri Precision RTS Glock 19 Gen 3 ZPS.3 Pistol Slide RMR Cut fits the Trijicon RMR. The RMR and RMRcc do not have the same mounting footprint. We do not have a specific mounting adapter for the Zaffiri Precision RTS Glock 19 Gen 3 ZPS.3 Pistol Slides to fit the RMRcc. I recomment contacting Zaffiri Precision for a compatible adapter or email us at techsales@opticsplanet.com so we can try to help find another adapter.
Please email us at techsales@opticsplanet.com regarding your question.
These Zaffiri Precision RTS Glock 19 Gen 3 ZPS.3 Pistol Slides will not work with a Glock 19 Gen 5. However, the Grey Ghost Precision Glock Version 4 Pistol Slide at the link below will work with a Glock 19 Gen 5.
