Glock 22 Gen 5 MOS OEM Slide – Overview

The Glock 22 Gen 5 MOS OEM Slide provides an optic-ready upgrade for shooters who run .40 S&W platforms. Because this slide features Glock’s Modular Optic System, it supports multiple red dot footprints using adapter plates. Additionally, the nDLC finish increases durability and corrosion resistance, making it ideal for duty use or heavy training.

Advantages of Factory Optic‑Ready (MOS) Slides

Choosing a factory optic‑ready Glock slide ensures reliability, perfect fitment, and long‑term durability. Glock’s MOS system is engineered to accept today’s most popular pistol red dots with secure mounting and no guesswork.

Key Benefits of a Factory MOS Slide

• Perfect OEM Fitment – Machined by Glock for exact tolerances, eliminating alignment issues seen in aftermarket cuts.

• Wide Optic Compatibility – Works with leading red dots like Trijicon RMR/SRO, Holosun 507C/508T, Leupold DPP, and more.
• Warranty‑Safe Upgrade – Using OEM MOS components avoids aftermarket modifications that may affect warranties.
• Enhanced Target Acquisition – Faster sight picture and improved accuracy in defensive or competitive shooting.

• Built for Gen 5 Reliability

specifically for Gen 5 frames, this slide features updated barrel geometry, a revised extractor system, and refined internal channels. These enhancements help produce smoother cycling and more stable shooting with .40 S&W ammunition, whether you use defensive loads or range rounds.
