Brownells Complete Slide Assembly With Threaded Barrel For Glock 19

Building or upgrading a Glock 19? The Brownells Complete Slide Assembly with Threaded Barrel gives you a fully assembled top half ready to drop onto a compatible frame. Unlike piecing together individual components, this slide arrives complete with barrel, sights, and internals already installed—no gunsmithing required. The threaded barrel accepts standard 1/2"-28 TPI suppressors, letting you run a can without adding bulk to your carry profile. Since the threads are on the muzzle itself rather than housing a separate compensator, your finished pistol still fits standard Glock 19 holsters.

The slide is machined from 416 stainless steel billet and finished with Black Nitride for durability and a refined look. It's cut for Trijicon RMR-pattern red dot optics and ships with a protective cover plate for the optic slot—mount a reflex sight now or later. Standard-height iron sights come installed and function as primary sights or reliable backups if you add a red dot. Front and rear cocking serrations, including a forward set for press-checks, provide solid grip and tactical functionality.

This assembly fits Gen3 Glock 19 factory frames and compatible aftermarket receivers. Everything you need is included: the match-grade threaded barrel, recoil spring assembly, sights, and all small parts. Just pair it with a frame, and you're ready to run. Note: installation requires a channel liner (press fit), and Brownells recommends part #777-100-017 for that job if you don't have the tool already.

What comes installed and what do I need to add?

The slide arrives fully assembled with the threaded barrel, both front and rear sights, recoil spring, and all internal small parts ready to go.
