What Is a Glock 43 MOS Slide?

A Glock 43 MOS slide is an optic-ready slide designed to accept red dot sights without extensive gunsmithing. Unlike a standard Glock 43 OEM slide, MOS and optic-cut slides feature precision machining that supports popular micro optics such as RMSc or RMR-style footprints. This makes them ideal for shooters looking to improve target acquisition and accuracy in compact platforms.

Many aftermarket options, including premium models, offer improved serrations, enhanced finishes, and weight-reducing cuts while maintaining factory tolerances.
