Glock 19 Gen 5 RMR Cut Slide | Red Dot Ready for Trijicon & Holosun
Glock 19 Gen 5 RMR Cut Slide – Optics-Ready for Red Dot Precision
Looking to upgrade your Glock 19 Gen 5 with a red dot-ready slide? Our RMR cut slide is purpose-built to fit Gen 5 G19 pistols and deliver precise, optics-compatible performance. Whether you're aiming for faster target acquisition or simply building a more versatile pistol, this slide gives you everything you need in a clean, drop-in design.
Designed for Glock 19 Gen 5 Frames
Unlike Gen 3 or Gen 4 slides, this model is machined to match the internal specs of the Gen 5 Glock 19 — including its updated recoil spring assembly and front frame rail configuration. That means proper fitment, reliable cycling, and zero compatibility issues.
Red Dot-Ready – Trijicon & Holosun Compatible
This slide comes pre-cut for the Trijicon RMR footprint, which also fits popular red dot sights like:
- Trijicon RMR & SRO
- Holosun 507C / 407C
- Other RMR-pattern optics
Direct-mounting your optic eliminates the need for adapter plates, giving you a lower profile and a more secure hold — ideal for both carry and competitive shooting.
Key Features
- RMR footprint optic cut – Mount your red dot directly
- Compatible with Gen 5 Glock 19 internals
- Front and rear serrations – Better slide control under pressure
- Optional window cuts – Lighter, faster cycling, and stylish design
- Durable finish options – Black nitride, FDE, and Cerakote finishes available
- Choose stripped or complete slide – Build your way
Stripped vs Complete Slide Options
- Stripped Slide: Great for custom builds. Requires your own internals, barrel, and guide rod.
- Complete Slide: Includes slide internals installed and ready to drop on your Gen 5 lower.
Whether you’re a DIY builder or want plug-and-play convenience, we’ve got you covered.

FAQs
Will this slide fit a Gen 3 or Gen 4 Glock 19?
No. It’s designed exclusively for Gen 5 Glock 19 pistols.
What red dots are compatible with the RMR cut?
This slide fits optics with the Trijicon RMR footprint — including the RMR, SRO, Holosun 507C, and 407C.
Do I need special sights for an RMR slide?
You can use standard sights, but suppressor-height sights are recommended for co-witnessing.
Is this slide ready to install out of the box?
