This stripped slide fits Glock 19 Gen 3 frames and matches Gen 3 internal dimensions — drop a Glock 19 Gen 3 barrel and slide completion kit into it and you have a complete upper ready to mate with your lower. Manufactured by Matrix Arms in New Hampshire from heat-treated stainless steel and finished in DLC (diamond-like coating) for surface hardness and a deep matte black look.

The slide is cut for the Trijicon RMR optic footprint directly — no plate, no adapter — and ships with diagonal front and rear serrations for press checks and slide manipulation. Sold as a stripped slide: no internals, no barrel, no cover plate. Pair it with a 3CR Tactical Slide Completion Kit (firing pin, extractor, plunger, cover plate, recoil rod) and a Glock 19 Gen 3 barrel of your choice to finish the upper.

• Fits: Glock 19 Gen 3 frames and Gen 3 components
• Material: heat-treated stainless steel
• Finish: DLC (diamond-like coating) — matte black
• Optic cut: Trijicon RMR footprint

Lightly oil the rails before assembly and verify your Glock 19 Gen 3 lower, barrel, completion kit, and optic footprint before installation. Run 50–100 rounds after the build to settle the slide and barrel before relying on the upper for carry or duty.
