Product Overview

The Glock 19 Gen 5 GNS OEM Complete Slide delivers factory accuracy and drop-in reliability in a compact, duty-ready package. Glock assembles the slide with a factory barrel, recoil spring assembly (RSA), and all required internals. Slip it onto a Glock 19 Gen 5 frame, mount sights or an optic, and the pistol is range- or duty-ready. This slide balances everyday carry, duty use, and range performance.

What the Glock 19 Gen 5 GNS Slide Is Made Of

Glock forges this slide from hardened, high-strength steel. The factory nDLC (nitride) finish resists wear, lowers friction, and provides strong corrosion resistance. Glock builds each component to OEM standards so the slide withstands heavy use and keeps consistent cycling and lockup.

Customizations & Upgrades

Popular Options

• Optic Mounting: Use compatible GNS plates or factory GNS cut for red-dot sights.
• Sights: Upgrade to night sights, steel three-dot, or low-profile suppressor-height sights.
• Finishes: Apply Cerakote or professional coatings for unique looks or extra protection.
• Professional Milling: Add ports or cosmetic cuts — use only certified gunsmiths.

Note: Permanent slide modifications may void the factory warranty and affect safety. Always use a qualified professional for advanced milling or optical installations.

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 19 Gen 5-compatible frame and magazine to function.

Q: Is it optic-ready?
A: Choose the GNS variant for factory optic cuts. Verify the model before ordering and use compatible optic plates.

Q: Can I use it on a standard Glock 19 Gen 5 frame?
A: Yes. The slide fits standard Glock 19 Gen 5 frames. For optics, verify frame/slide compatibility or pair with a GNS-capable frame.

Q: Does it include sights?
A: The slide ships with factory sighting interface (dovetail or GNS-ready). You can swap to night sights or other aftermarket options.

Q: Do I need a gunsmith for installation?
A: Most users perform a drop-in installation following Glock’s instructions. Use a professional for optic mounting, sight zeroing, or custom milling.

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