What the Glock 19X MOS OEM Slide Is Made Of

Glock forges the 19X slide from hardened, high-strength steel and applies an nDLC finish for wear resistance, reduced friction, and corrosion protection. Glock builds every component to OEM quality standards so the slide handles thousands of rounds while keeping consistent function.

Customizations & Upgrades

Popular Options

• Optic Plates: Fit a red-dot using the correct MOS plate for your optic.
• Sights: Swap to night sights or fiber-optic dovetail replacements.
• Finishes: Apply Cerakote or other custom coatings for a unique look or extra protection.
• Professional Milling: Add ports or cosmetic cuts only through a certified gunsmith.

Note: Permanent slide modifications may void the factory warranty and affect safety. Use a qualified professional for advanced work.

FAQs

Q: What does NTB mean?
A: NTB stands for a non-threaded barrel — the barrel has no external threads for muzzle devices.

Q: Is this slide optic-ready?
A: Yes. The MOS designation means Glock cuts the slide to accept optic plates; install the correct plate for your red-dot model.

Q: Will this fit a standard Glock 19 frame?
A: No. The 19X uses full-size slide geometry and specific dimensions. Confirm fitment before purchase.

Q: Does it include sights?
A: Yes. The slide ships with factory dovetail sights installed. Replace them with aftermarket options if you prefer.

Q: Do I need a gunsmith for installation?
A: Most users can perform a drop-in installation following Glock’s guidelines. Hire a professional for optic mounting, sight zeroing, or permanent modifications.

Q: Is the nDLC finish durable?
A: Yes. Glock applies an nDLC finish that improves surface hardness, lowers friction, and resists corrosion.
