What the Glock 34 Gen 5 MOS Slide Is Made Of

Glock forges the 34 Gen 5 MOS slide from high-strength OEM steel. In addition, the factory nDLC finish enhances hardness, reduces friction, and protects against corrosion. As a result, each slide maintains reliable performance, smooth cycling, and consistent accuracy over thousands of rounds. Moreover, every component meets Glock’s strict Gen 5 factory standards, ensuring long-term durability and dependable function.

Customizations & Upgrades

Popular Options

• Optics: Add red-dots using Glock MOS plates (sold separately)
• Sights: Upgrade to night sights or fiber-optic replacements
• Finishes: Apply Cerakote or custom coatings for added durability and style
• Professional Milling: Add ports or cosmetic cuts with certified gunsmiths

Note: Permanent modifications may void the warranty. Always consult a qualified professional before advanced work.
