Optics Ready with Modular Optic System (MOS)

The Glock 43X MOS features Glock’s factory Modular Optic System, allowing shooters to easily mount a wide variety of popular red dot sights without the need for custom milling. Whether you prefer a Trijicon RMR, Holosun 507K, Sig Romeo Zero, or another micro red dot optic, the MOS slide provides a secure and reliable mounting platform. This optics-ready design dramatically improves target acquisition speed and accuracy, especially in dynamic shooting situations or low-light conditions. The MOS configuration makes the Glock 43X MOS future-proof and highly customizable for modern shooters who want the advantage of a red dot sight on a slimline pistol.

Front Accessory Rails for Enhanced Versatility

In addition to the MOS system, this model includes front accessory rails on the frame. These rails allow users to mount weapon lights, lasers, or other accessories, greatly expanding the pistol’s utility for home defense and low-light applications. The combination of optics readiness and front rails makes the Glock 43X MOS one of the most adaptable slimline 9mm pistols available, offering both modern sighting options and the ability to add illumination when needed.

US-Made Glock 43X with Increased Capacity

US-made Glocks are highly regarded for their strict quality control and compliance with American manufacturing standards.
