What the Glock 34 Gen 3 OEM Slide Is Made Of

Glock machines the Gen 3 G34 slide from hardened, high‑strength steel. The factory nDLC (nitride) finish protects the steel, resists corrosion, and reduces friction. Glock’s manufacturing standards ensure long service life, precise lockup, and dependable performance, even under heavy use.

Customizations & Upgrades

Popular Options

• Sights: Upgrade to fiber-optic or night sights for faster target acquisition.
• Optic Mounting: Add a dovetail‑mount red dot or choose a gunsmith‑installed optic cut.
• Slide Finish: Add Cerakote or custom coatings for unique style and more durability.
• Milling: Add ports or slide cuts (professional work only).

Note: Permanent slide modifications may void the Glock warranty. Always use a certified gunsmith.
