Glock 79011 Spare Slide Fits Glock 34 Gen3 Black Matte Optic Ready Slide

The Glock 79011 spare slide is an OEM-spec replacement designed for Glock 34 Gen3 pistols. If you're building a backup gun, running a competition setup, or need to swap in a fresh slide, this factory-direct component gives you the reliability Glock is known for—without compromise. It comes assembled with internals and finished in black matte, and it's cut for optics mounting, so you can run a red dot on your duty or range gun.

Sourcing OEM Glock parts matters. This slide is made to the same tolerances and standards as every other Glock component that comes from the factory, which means fit, feeding, and longevity are locked in. Whether you're a competitive shooter building a dedicated race gun, a duty officer looking for a battle-proven backup, or a serious enthusiast who maintains multiple setups, this is the part to trust.

What you get in the box is the slide itself, fully assembled with all internal parts, plus a cover plate for the optics cut—everything you need to mount a compatible sight. Note that you'll source your barrel and recoil spring assembly separately, and if you plan to use MOS adapter plates for a specific optic footprint, those are sold as standalone items.

Frequently Asked Questions

Will this slide fit my Glock 34 Gen3 frame?

Yes. This is an OEM replacement slide engineered for Glock 34 Gen3 frames. It will function as a direct swap as long as you have a compatible barrel and recoil spring assembly.

Is this slide optics-ready, and what mounts does it support?

Yes, the slide features the Glock MOS (Modular Optics System) cut and includes a cover plate. MOS adapter plates (sold separately) allow you to mount red dots and reflex sights with different footprints; check your specific optic's compatibility before ordering adapters.

What parts do I need to buy separately?

The slide comes with internals and a cover plate, but you will need to source a barrel, a recoil spring assembly, and (if using an optic) any MOS adapter plates that match your sight. All are available separately.

Is this a factory OEM part?

Yes. This is manufactured by Glock to the same specifications and quality standards as OEM Glock pistol components, ensuring reliable fit and function.
