Glock 17 Gen 3 Complete MOS Slide, Black Matte

This Glock 17 Gen 3 Complete MOS Slide (brand part number 79009) is a factory Glock spare slide finished in black matte and cut for the Modular Optic System, so it’s ready for a red dot out of the box. It ships fully assembled with internals installed, along with the MOS cover plate and Glock’s standard factory sights, so there’s nothing else to source before you install it. Because it’s a slide-only assembly, it’s not a regulated firearm and does not require an FFL transfer. It’s a straightforward way to build a dedicated optic-ready slide for your Glock 17 Gen 3 without sending your only slide out for milling.
