The Brownells Complete Window Slide Assembly with Ported Barrel for Glock 19 is a fully machined, pre-assembled slide package built for shooters who want to reduce muzzle rise without adding length to their carry gun. This complete slide assembly comes ready to drop onto a compatible Gen3 Glock 19 frame or aftermarket clone, making it an ideal choice for custom pistol builds, performance upgrades, or those who want a finished top half without the assembly work. The ported barrel design vents through a window cut into the top of the slide—a clever engineering solution that keeps your pistol compatible with standard holsters while managing recoil.
Built from 416 stainless steel billet and finished in hard Black Nitride, this slide is machined to factory Glock specifications internally while offering refinements externally. The ported barrel features eight ports angled to counteract muzzle rise and help you stay on target for follow-up shots. A pre-cut Trijicon RMR footprint lets you mount a modern red dot sight, and Brownells includes a reinforced polymer cover plate if you're not ready to add an optic yet. The slide ships complete with match-quality barrel, front and rear sights, small parts, recoil spring assembly, and optic cover—everything you need except the frame.
Racking the slide is straightforward thanks to wide, shallow cocking serrations on the rear and mirrored serrations up front for press-checking. The standard-height iron sights work as primaries or backups when paired with a red dot. Note that a channel liner (sold separately) is required for installation on a frame and requires a press tool to fit.

| Platform | Glock 19 Gen3 / Compatible Frames |
| Slide Material | 416 Stainless Steel Billet |
| Finish | Black Nitride |
| Barrel Type | Ported (8 ports) |

This complete slide assembly is designed to fit Gen3 Glock 19 pistols and compatible aftermarket frames that accept Gen3 Glock 19 slides. You will need a channel liner (sold separately) to complete the installation, which requires a press tool.
The package includes the fully assembled slide with ported barrel, match-quality barrel, front and rear iron sights, small internal parts, recoil spring assembly, and an optic cover plate for the RMR footprint slot. It arrives ready to install on a compatible frame.
The eight ports angled into the ported barrel vent gases upward through the window in the slide, providing a counterforce that reduces muzzle rise and helps you maintain sight picture for faster, more accurate follow-up shots. This approach keeps the gun short enough to use standard holsters, unlike a muzzle-mounted compensator.
Yes. The slide comes with a pre-cut mounting slot that accepts reflex sights with a Trijicon RMR footprint. Brownells includes a reinforced polymer cover plate to fill the slot if you're not ready to mount an optic.
