Fits Glock 19 Gen 1, Gen 2, and Gen 3 OEM frames plus Polymer80 PF940C and GST-9 builds. Will not fit Gen 4 or Gen 5 frames. DLC is the hardest aftermarket finish you can put on a Glock slide — bonded to the steel at the molecular level, it does not chip or flake the way Cerakote can on edges and corners.

Slide specs:

• Finish: hard black DLC (Diamond-Like Carbon) — extreme surface hardness, low friction, corrosion-resistant
• Optic cut: Trijicon RMR footprint — accepts RMR, Holosun 407/507, and compatible micro-red-dots
• Iron sight cuts: standard Glock dovetail front and rear
• Front and rear diagonal serrations — positive grip for press checks and administrative handling
• Matching RMR cover plate installed (protects the cut during storage and use without an optic)
• Chambering: 9mm

What you still need: a 9mm barrel and a slide completion kit (internals). This is a bare slide — pair it with the 3CR Slide Completion Kit and a Gen 3 G19 barrel to finish the build.

DLC vs. Cerakote vs. Nitride: DLC outperforms nitride in surface hardness and corrosion resistance, and it does not chip the way Cerakote can on the muzzle, slide stop, or rear corners. It is the right choice if this slide is going on a carry gun or a build that will see regular range time.

Break-In: Lubricate the rails before first installation. Hand-cycle the slide 50 times after assembly to verify smooth lockup and barrel hood timing before live-fire.
