How to Install the Glock 17 Gen 5 MOS OEM Complete Slide

Safety First

Work on a clean area, wear eye protection, and confirm the firearm is unloaded. Follow all laws and manufacturer guidelines. If unsure, ask a qualified gunsmith.

Drop-In Installation

2. Unload the firearm completely — remove magazine and check the chamber.
3. Align the slide with the frame rails and rack it into position.
4. Perform a basic function check (per local laws): rack, lock, and dry-fire to confirm movement.
5. If you mount a new optic or sights, confirm zero at the range.
6. Stop immediately if anything feels abnormal and contact a gunsmith.

How to Disassemble the Glock 17 Gen 5 MOS Slide 

1. Remove magazine, lock slide open, and verify the chamber is empty.
2. Follow Glock takedown steps to remove the slide from the frame.

5. Reassemble in reverse order or seek help from a professional for deeper service.

What Is the Glock 17 Gen 5 MOS Slide Made Of?

Glock builds the Gen 5 MOS slide from high-strength steel and finishes it with a factory nDLC coating. This finish boosts surface hardness, resists corrosion, and reduces glare. All internals meet factory standards for reliable cycling and consistent performance.

Customizations & Upgrades

Common Options

• Optics: Mount a red-dot using the correct MOS plate.
• Sights: Upgrade to night sights or fiber-optic dovetail sights.
• Coatings: Cerakote or refinishing for custom colors and added protection.
• Professional Milling: Custom cuts or ports (may affect warranty; use a trusted gunsmith).

Note: Permanent modifications can impact safety and warranty.
