What Is The Glock 43X OEM Slide Made Of

Glock uses high-strength steel to build the 43X  slide. The nDLC finish improves durability, resists corrosion, and reduces glare. Glock engineered this finish to perform in harsh environments.

Customizations

• Sights: Dovetail sights or OEM sight swaps.
• Optic plates: Use only if the slide is cut or you have the correct plate.
• Coatings: Cerakote or professional refinishing for color and protection.
• Professional milling: Windows, serrations, or lightening cuts — have done by a reputable shop.

Note: Permanent milling or structural changes can affect safety and warranty. Use a qualified gunsmith.

FAQs

Q: Is this ready to fire out of the box?

No — it’s a stripped slide. You need a barrel, recoil spring, and internals.

Most OEM 43X barrels fit. Confirm generation and part numbers first.

Q: Can I add a red-dot optic?

Only if the slide is optic-ready or professionally milled for that optic.

Q: Do I need a gunsmith?

If you’re not confident following Glock’s manual, yes — use a qualified gunsmith.
