The Brownells Window Slide Assembly for Glock 19 with RMR cut transforms your Gen3 G19 into a modern, optics-ready platform without sacrificing the simplicity of iron sights. This precision-machined slide accepts Trijicon RMR-footprint reflex sights, making it an excellent choice for shooters who want to run a red dot on a compact carry or competition pistol while maintaining factory ergonomics and holster compatibility. Whether you're building a custom pistol from the frame up or upgrading an existing Glock 19, this slide delivers both form and function.
What sets this assembly apart is the distinctive window cutout along the top, which serves practical and aesthetic purposes. The opening promotes cooling during sustained shooting—ideal for competitors running hard drills—and lets you showcase an upgraded or ported barrel without the bulk of a muzzle compensator. If you install a ported barrel, exhaust gases venting through the window help control muzzle rise, keeping your sights on target for follow-up shots. A lightweight polymer cover plate is included to cap the RMR slot if you're not mounting an optic yet, so you can run iron sights alone or add a red dot later.
Built from 416 stainless steel billet and finished in durable black Nitride, the slide is machined to factory Glock specifications internally, so it pairs seamlessly with factory or quality aftermarket G19 barrels and small parts. The front and rear iron sights are factory-height, ready to serve as primaries or reliable backups. Wide, shallow cocking serrations at the rear and a mirrored set forward make slide manipulation smooth and confident from any angle or shooting position.
This is a quality component for the serious Glock 19 builder or upgrader who wants a slide that balances modern optics mounting with traditional reliability and practical shooting performance.

Yes, this slide is designed for Glock 19 Gen3 pistols and compatible aftermarket frames. The internal dimensions are machined to factory Glock specifications, so it will accept factory or quality aftermarket G19 barrels and small parts. A channel liner is required for installation (sold separately).
The slide is cut for optics that use the Trijicon RMR footprint. If you're not mounting an optic immediately, the included polymer cover plate closes off the slot neatly.
Yes. The window cutout allows combustion gases venting from a ported barrel to exit through the top, which can help counteract muzzle rise during rapid fire. The window design also keeps your custom or ported barrel visible, and eliminates the need for a bulky muzzle compensator, so your pistol will still fit standard Glock 19 holsters.
Factory-height front and rear iron sights are installed and ready to use. They function as primary sights if you run iron only, or as reliable backups when paired with an RMR-footprint red dot.
