1. Confirm the slide matches your Glock 45 frame.
2. Remove the magazine and verify the chamber is empty.
3. Align the slide on the frame rails and gently rack it into place.
4. Perform a basic function check: rack the slide, test slide lock, dry-fire where legal, and verify proper reset and slide movement.
5. If you mount an optic, follow the optic manufacturer’s torque and installation guidelines.
6. Perform a live-fire test at a safe range before relying on the firearm for duty or carry.

How to Disassemble the Glock 45 MOS Slide (Maintenance & Service)

Routine Disassembly (Overview)

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

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

What the Glock 45 MOS Slide Is Made Of

Glock forges the 45 MOS slide from hardened, high-strength steel. The factory nDLC (nitride) finish increases surface hardness, lowers friction, and resists corrosion. Glock machines each part to OEM quality to give consistent function shot after shot.

Customizations & Upgrades

Popular Options

• Optic Mounting: Add a red-dot using MOS-compatible optic plates.
• Sights: Swap to night sights or fiber-optic dovetail replacements.
• Finishes: Apply Cerakote or custom coatings for unique looks or extra 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 you need a Glock 45-compatible frame and magazine for the firearm to function.

Q: Is it optic-ready?
A: Yes. This MOS variant ships with a factory-cut MOS pattern. Buy the correct optic plate and red-dot to match your optic.

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 compatible MOS plates.

Q: Does it include sights?
A: Yes. The slide ships with factory 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: Many users perform a drop-in installation following Glock’s instructions. Hire a professional for optic mounting, sight zeroing, or advanced gunsmithing.

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