Diamond grip vs. standard serrations

The diamond texture is machined directly into the slide, giving purchase across the entire serration zone rather than at a few discrete ledges. The result is more positive press checks and support-side manipulations — a practical advantage for support-hand work and in wet or gloved conditions.

Optic Mounting Hardware

• Cover plate screws: 6-32 × 1/3"
• Optic mount screws: 6-32 × 7/16"

For optic installation, use the mounting kit included with your optic (Holosun, Trijicon, Sig, Vortex, etc.) — manufacturer kits have the correct torque spec, head shape, and threadlocker matched to that optic. The dimensions above are for reference when sourcing a replacement cover plate or aftermarket hardware. Optic mounting hardware is not included with this slide.

Break-in and care

Lube all slide rails and contact surfaces before first use. Run approximately 200 rounds of standard 9mm ammunition during break-in before moving to duty or self-defense loads. Confirm your lower is a Glock 19 Gen 3 pattern before fitting.
