What the Glock 23 Gen 5 OEM Slide Is Made Of

Glock machines the Gen 5 slide from hardened, high-strength steel. The nDLC finish protects against corrosion, adds surface hardness, and reduces wear. Each part meets OEM standards to ensure smooth cycling and long service life.

• Finishes: Apply Cerakote or custom coatings for protection or style

FAQs

Is this slide ready to use?

Yes. It ships fully assembled with the barrel and internals. It still needs a Glock 23 Gen 5 frame and magazine.

Is it optic-ready?

Standard slides use dovetail sights. The MOS version supports red-dot optics.

Does it fit all Glock 23 frames?

It fits only Gen 5 Glock 23 frames.

Does it include sights?

Yes. Glock installs factory polymer sights. You can replace them.

Do I need a gunsmith to install it?

Most users install it without tools. Use a professional for optic mounting or sight zeroing.

Is the nDLC finish durable?

Yes. It improves hardness, lowers friction, and resists corrosion.
