    Glock 43X MOS 9mm Accessory Compatibility & Recommendation Guide

    Product Compatibility Overview

    The Glock 43X MOS 9mm is a compact, optics-ready pistol designed for concealed carry and personal defense. The "MOS" (Modular Optic System) variant features a factory-milled slide for direct mounting of micro red dot sights. The pistol uses the Slimline frame, which impacts compatibility with certain accessories compared to standard Glock models.

    Mounting Systems:

    • Optics: MOS cut for Shield RMSc footprint (and compatible micro red dots)
