Product Description | Specs for Glock 34 Gen 5 MOS OEM Slide

Glock machines this slide from high-strength steel and applies a rugged nDLC (diamond-like carbon) finish for superior wear and corrosion resistance. Designed with the MOS (Modular Optic System), the slide accepts adapter plates for common micro red-dot footprints. Its extended length improves accuracy and recoil control, while Glock’s proven internal geometry ensures consistent cycling and reliability.
