Brownells
The Brownells Slide Assembly for Glock 19 with RMR cut is a machined-from-billet upgrade slide engineered for shooters who want modern optics capability without abandoning their iron sights. Built on a Gen3 Glock 19 platform, this slide ships pre-cut to accept Trijicon RMR-footprint reflex sights, making it an excellent foundation for a duty-ready, competition, or custom pistol build. Whether you're retrofitting a factory G19 or assembling from scratch on a compatible frame, this slide delivers the ergonomics and mounting versatility that come standard in modern tactical handguns.
Machined from 416 stainless steel billet and finished in black Nitride for durability, the slide maintains full factory-spec internal dimensions—meaning it'll run factory or aftermarket barrels and small parts without hassle. The included optic slot cover plate lets you run it without a red dot if you choose, and factory-installed front and rear iron sights serve double duty: primary sights in traditional setups, backup irons when paired with a mounted optic. Wide, shallow rear cocking serrations and matching front serrations give you confident purchase from any grip angle or shooting position, whether you're racking or press-checking the chamber.
Brownells offers two configuration options: a solid-top slide for a traditional profile, or a window-cutout version that opens the top. That window serves form and function—it shows off a custom barrel finish, fluting, or porting, and more importantly, it allows gas venting from a ported barrel to naturally counteract muzzle rise without requiring a muzzle-mounted compensator. That means your finished pistol still fits standard Glock 19 holsters.
Assembly includes a recoil spring, cover plate, and all fasteners needed to mount it on a compatible frame. Note that a channel liner (sold separately) is required and press-fit installation is recommended with the proper tool.
| Platform | Glock 19 Gen3 |
| Material | 416 Stainless Steel (billet machined) |
| Finish | Black Nitride |
| Optic Mount | Trijicon RMR footprint |
| Sights | Factory-height front and rear iron sights (installed) |
| Serrations | Rear cocking serrations and front press-check serrations |
| Configuration Options | Solid top or window cutout |
| Included Accessories | Recoil spring assembly, optic slot cover plate |
Yes. This slide is machined to full Glock factory Gen3 specifications internally and works with standard factory Glock 19 frames as well as quality aftermarket frames designed for the Gen3 platform.
The slide features a pre-cut mounting slot for reflex sights with the Trijicon RMR footprint. It ships with a polymer cover plate that fills the slot if you're not mounting an optic immediately.
Absolutely—the slide comes with factory-height front and rear iron sights fully installed. You can run it as a traditional iron-sight pistol right out of the box, or add a compatible optic later.
The solid-top slide has a traditional full-length top surface. The window-cutout version opens the top of the slide, allowing you to display custom barrel finishes, fluting, or porting details. The window also permits gas venting if you install a ported barrel, which naturally reduces muzzle rise without a muzzle device, and your pistol will still fit standard Glock 19 holsters.
Yes. A channel liner is required for operation and is sold separately. It is a press fit that requires a tool to install properly. Brownells recommends using the correct installation tool for this task.
