The Glock 43X MOS is already a standout in Glock’s lineup, combining the slim, carry-friendly profile of the 43X with the added versatility of the Modular Optic System. This particular configuration takes the platform to a new level, coming outfitted with a Holosun EPS red dot sight mounted directly to the slide, and finished in a striking coyote brown. The combination of Glock’s reliability, modern optics, and a unique colorway makes this a highly capable choice for everyday carry, personal defense, and tactical applications.

At its foundation, the Glock 43X MOS is a 9mm single-stack pistol with a 3.41-inch barrel, offering a compact yet highly functional platform. With a 10+1 round capacity, it balances concealability with effective firepower, making it ideal for concealed carry or a backup gun. The MOS (Modular Optic System) cut on the slide allows for the direct installation of micro red dots, removing the need for aftermarket machining and providing a true factory-level optic-ready experience. In this case, the pistol comes paired with a Holosun EPS red dot sight, a model known for its durability, crisp reticle, and extended battery life. The carry-sized EPS is designed to withstand daily use while enhancing speed and accuracy in target acquisition.

The coyote brown Cerakote finish is not just for aesthetics, it also offers excellent corrosion resistance and pairs well with those who already have the Glock 19X. Paired with textured grip panels and the slim Glock ergonomics, this model remains highly comfortable in hand while still offering the secure control necessary for confident shooting. Glock’s signature polymer frame keeps the weight low, enhancing carry comfort without sacrificing structural integrity or reliability.

From a practical standpoint, the inclusion of the Holosun EPS red dot transforms the way shooters interact with the 43X MOS. Red dots increase accuracy potential, particularly in dynamic or low-light scenarios, and the MOS configuration allows shooters to easily swap optics should they wish to try different reticle options or brands. With the Holosun mounted, users benefit from rapid target acquisition, which is particularly useful for defensive applications where split-second decisions matter. The slide retains Glock’s proven reliability, crisp trigger, and smooth cycling, meaning the optic complements rather than compromises the pistol’s performance.

Additional enhancements, such as the Glock Marksman Barrel and ambidextrous slide stop, ensure that this 43X MOS remains capable and adaptable to the shooter’s preferences. With a 3.41-inch barrel, the pistol balances concealability with ballistic performance, while the slim frame ensures it can be comfortably carried for extended periods. Whether you’re a concealed carry enthusiast looking for a reliable, optic-ready platform or a Glock collector seeking a unique configuration, the 43X MOS with Holosun EPS and coyote brown finish delivers both style and substance.
