What Is the Glock 49 Gen 5 MOS OEM Slide Made Of?

Glock crafts the slide from hardened steel and applies an nDLC finish for increased surface hardness, reduced friction, and excellent corrosion resistance. The finish helps the slide endure heavy use while keeping a low-glare profile.

Customization Options

• Optics: Mount Trijicon RMRcc, Holosun 507K/407K, Shield, or other MOS-compatible micros using included plates.
• Sights: Swap factory sights for low-profile suppressor-height, night, or fiber-optic sights for co-witnessing.
• Finish: Have a professional applicator Cerakote or recoat for color customization (note: refinishing may affect warranty).
• Milling/Engraving: Authorize a qualified gunsmith for additional milling or engraving (unauthorized milling may void warranty).

FAQs

Q: Does the complete slide include MOS adapter plates?
A: Yes — Glock typically includes numbered MOS adapter plates and mounting screws with the complete MOS slide.

Q: Can I mount every micro-dot with the MOS plates?
A: The MOS plate set covers the most common footprints. Verify plate selection and screw lengths for your specific optic prior to mounting.

Q: Is this slide compatible with Gen-4 or Gen-3 frames?
A: No. Glock designed this slide for Gen-5 frames. Mixing generations can cause fit and function issues.

Q: Will mounting an optic void the warranty?
A: Mounting an optic with the factory MOS system does not void the slide’s intended use. However, third-party machining or unauthorized modifications may impact warranty coverage.

Q: Does the stripped slide include sights?
A: Yes — most stripped MOS slides ship with factory front and rear sights and the channel liner.
