What the Glock 19 Gen 5 MOS Slide Is Made Of

Glock forges the 19 Gen 5 slide from hardened, high-strength steel. The factory nDLC finish reduces friction, resists corrosion, and increases surface hardness. Glock builds every component to OEM quality standards so the slide withstands high round counts and maintains consistent function.

Customizations & Upgrades

Popular Options

• Optic Mounting: Install a red-dot using compatible MOS plates (choose the correct plate model).
• Sights: Swap to night sights or fiber-optic dovetail replacements.
• Finishes: Apply Cerakote or custom coatings for a unique appearance (use a qualified applicator).
• Porting / Cuts: Add lightening cuts, ports, or aesthetic milling — use only certified gunsmiths.

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

FAQs

Q: Is this slide ready to fire out of the box?
A: The slide ships fully assembled with barrel and internals, but it needs a Glock 19 Gen 5-compatible frame and magazine to function.

Q: Is it optic-ready?
A: Yes. This MOS variant features Glock’s Modular Optic System cut and accepts compatible optic plates. Verify plate compatibility for your optic.

Q: Can I use it on a standard Glock 19 Gen 5 frame?
A: Yes. The slide fits Glock 19 Gen 5 frames. For best results, verify slide-to-frame fit and function.

Q: Does it include sights?
A: Yes. The slide ships with factory-installed dovetail sights. You can swap them for night sights or remove them to mount certain optics or covers.

Q: Do I need a gunsmith for installation?
A: Most users can perform a drop-in installation following Glock’s instructions. Seek a professional for optic mounting, plate fitting, or sight zeroing.

Q: Is the nDLC finish durable?
A: Yes. The nDLC (nitride) finish increases surface hardness, reduces friction, and resists corrosion.
