G34 Gen3 Spare Slide with Standard MOS Cut — Optic-Ready Replacement Slide for Serious Shooters

Upgrade your Glock G34 Gen3 with a premium, optic-ready spare slide designed to maximize speed, accuracy, and modularity. The G34 Gen3 Spare Slide with Standard MOS Cut features factory-style MOS (Modular Optic System) technology for fast, secure red-dot mounting, aggressive front serrations for quicker slide manipulations, and fully assembled internals so you can get back to the range or the match in minutes. Whether you’re building a dedicated competition gun, prepping a backup slide for training, or replacing a worn slide with something better-than-factory, this spare slide delivers the performance and versatility you expect from top-tier Glock spare slides.

Built with precise machining and true-to-spec dimensions, the slide accepts standard Glock sights and comes with a MOS cover plate included so you can protect the optic cut when not in use. The slide arrives with assembled internals for drop-in convenience—just add your barrel and recoil assembly and you’re ready to go. Front serrations provide confident purchase for press checks and rapid transitions, while the MOS cut gives you a secure platform for most red dot footprints (adapter plates sold separately).

Why choose this spare slide? It’s a quick, cost-effective way to convert a standard G34 Gen3 into an optics-ready platform without permanently modifying your existing pistol. Carry it as a spare, keep one for competition, or configure it as a suppressed or comp-ready rig — the modularity is in your hands. And because it’s purpose-built for the G34 Gen3 form factor, you’ll enjoy consistent lockup and reliable cycling with properly selected components.
