Routine Disassembly (Overview)

1. Remove magazine and lock the slide open; confirm the chamber is empty.
2. Follow Glock takedown steps to separate the slide from the frame.
3. Remove the recoil spring assembly and barrel for cleaning.

5. Clean, lubricate, and reassemble in reverse order.
6. For deeper work or part replacement, consult a qualified armorer or gunsmith.

What the Glock 45 OEM Slide Is Made Of

Glock forges the 45 slide from hardened, high-strength steel. The factory nDLC (nitride) finish resists wear, reduces friction, and provides strong corrosion resistance. Glock builds every component to OEM quality standards so the slide handles thousands of rounds and keeps consistent function.

Customizations & Upgrades

Popular Options

• Optic Mounting: Add a red-dot using compatible optic plates (choose MOS variants if you need factory cuts).
• Sights: Swap to night sights or fiber-optic dovetail replacements.
• Finishes: Apply Cerakote or custom coatings for a unique look or added protection.
• Professional Milling: Add ports or cosmetic cuts — 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 45-compatible frame and magazine to function.

Q: Is it optic-ready?

A: Standard Glock 45 slides use dovetail sights. If you need an MOS optic cut, choose the Glock 45 MOS variant and confirm compatibility.

Q: Can I use it on a standard Glock 45 frame?

A: Yes. The slide fits Glock 45 frames. For optics, verify your frame supports the optic or use a MOS slide/frame combo.

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.

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, sight zeroing, or advanced milling.

Q: Is the nDLC finish durable?

A: Yes. The nDLC (nitride) finish improves hardness, lowers friction, and resists corrosion.
