This is the complete package for your Glock 19 Gen 3 build — slide, barrel, internals, and sights. Pull it out of the box, drop it on your frame, add lube, and run it. Nothing left to source.

Everything that comes installed:

• Full-length 9mm black nitride barrel — flush crown, tight tolerances
• Trijicon RMR footprint cut — mounts any standard RMR/micro-red-dot footprint optic
• Tall co-witness sights — iron sight picture maintained with optic mounted
• Front and rear diagonal serrations — reliable grip in any condition
• All internal components pre-installed — trigger, extractor, firing pin, spring, recoil rod

Compatibility:

• Glock 19 Gen 1, Gen 2, Gen 3 OEM frames
• Polymer80 PF940C and GST-9 frames
• Not compatible with Gen 4 or Gen 5 frames

What to know before ordering:

Lube the rails before your first use. Expect a 200–300 round break-in before the action is fully smooth. If you prefer a different barrel finish — TiN, fluted, threaded — see the BYO Glock 19 Slide Configurator to spec exactly what you want.
