Glock 26 Gen 5 OEM MOS Slide

Upgrade your compact Glock with the Glock 26 Gen 5 OEM MOS Slide — a factory optic-ready slide that brings Gen-5 refinements and fast target acquisition to your subcompact carry gun. Glock machines the slide to strict tolerances, adds front serrations for secure manipulations, and includes the MOS (Modular Optic System) cut so you can mount a micro red dot quickly and securely.

Product Description | Specs for Glock 26 Gen 5 OEM MOS Slide

Glock forges this slide from high-strength steel and finishes it with a durable nDLC coating that resists wear and corrosion. The MOS cut accepts common micro-red-dot footprints via adapter plates. Front serrations improve gripping during press checks and slide racking. The slide accepts the Glock Marksman Barrel (GMB) for improved accuracy and consistent lockup.

What Is the Glock 26 Gen 5 MOS OEM Slide Made Of?

Glock machines the slide from hardened steel and applies the nDLC finish to add surface hardness, reduce friction, and resist corrosion and wear. The finish also reduces glare for tactical and competition use.

Customization Options

• Optics: Mount Trijicon RMRcc, Holosun 507K/407K, Shield RMSc (use supplied adapter plates).
• Sights: Swap to low-profile suppressor-height sights or night sights for co-witnessing.
• Finish: Professional Cerakote or additional coatings (note: refinishing may affect warranty).
• Milling/Engraving: Have a qualified armorer add cuts or engravings (milling OEM slides can void manufacturer warranty).

FAQs

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

Q: Can I mount any micro red dot?
You can mount most micro-red-dot optics that match the MOS adapter plate footprints included. Verify screw lengths and plate selection before mounting.

Q: Is this slide compatible with Gen-4 or Gen-3 frames?
No. This slide targets Gen-5 frames and Gen-5 parts. Mixing generations can cause fit and function issues.

Q: Will mounting an optic void my warranty?
Mounting optics using Glock’s MOS system does not void the slide itself, but third-party milling or unauthorized modifications may affect warranty. Always follow manufacturer instructions.

Q: Does the stripped slide come with sights?
Yes — the stripped MOS slide normally ships with factory front and rear sights and the channel liner.
