Glock OEM MOS Slide For G19 Gen 3

This factory Glock OEM MOS slide is a drop-in replacement for Glock 19 Gen 3 pistols, built to original Glock specifications for maximum reliability and fit. It features Glock’s Modular Optic System (MOS), allowing you to easily mount a variety of popular red dot optics without additional machining, making it ideal for shooters upgrading a duty gun, carry pistol, or range setup. The slide includes factory-installed internal components, standard Glock sights, and an MOS cover plate, so it is ready to pair with your existing G19 Gen 3 frame, barrel, and recoil spring assembly.

Precision-machined with the factory MOS optic cut, this slide gives you a clean, low-profile mounting solution while maintaining Glock’s legendary durability and function. Front serrations provide faster, more secure manipulations for press checks and malfunction clearance, especially in adverse conditions or under time pressure. The robust factory finish is designed to resist wear and corrosion from daily carry, training, and hard use, ensuring long service life and consistent performance.

As a genuine Glock OEM component, this MOS slide ensures proper fit, safe operation, and compatibility with Glock 19 Gen 3 frames, unlike many aftermarket options. It is an excellent choice for replacing a worn or damaged slide, converting a standard G19 Gen 3 to an optic-ready configuration, or starting a high-reliability custom build. Barrel, recoil spring assembly, and MOS adapter plates are sold separately, giving you the flexibility to choose your preferred barrel and optic mounting plate for your specific red dot sight.
