Factory Glock spare slide for G17 Gen 3 with Modular Optic System (MOS) cut for red dot mounting. Includes assembled internals, cover plate, and standard sights.
This factory Glock spare slide transforms your Gen 3 Glock 17 into an optic-ready platform. The Modular Optic System (MOS) cut allows you to mount popular red dot sights without gunsmithing or additional modifications.
A spare slide lets you maintain your pistol while keeping it in service, or quickly switch between iron sights and optic configurations. This is the same quality slide found in factory Glock pistols.
