Advantages of Holosun Optics for Glock 43X MOS
Faster Target Acquisition
A Holosun optic helps you find and stay on target more quickly than standard iron sights. The bright dot gives you a clear point of focus, which makes shooting smoother and more accurate in high-pressure situations.
Long Lasting Power
Battery life is one of Holosun’s biggest strengths. Many models provide up to 50,000 hours of runtime. Features like Shake Awake and Solar Failsafe add even more reliability, so your sight is ready when you need it.
Compact and Concealable
The Glock 43X MOS is made for carry, and Holosun optics match that purpose. Their slim and lightweight design keeps your pistol easy to conceal without adding bulk, which is important for daily use.
Strong and Durable Build
Holosun optics are built from 7075 aluminum housings that can handle recoil, impact, and harsh conditions. This makes them dependable tools whether you are at the range, outdoors or carrying every day.
Multiple Brightness Settings
Lighting can change quickly, but a Holosun optic adapts. With up to 12 brightness settings, including options for low light and night vision, you always get a reticle that is visible and comfortable to use.
User Friendly Design
Holosun sights are built for convenience. Side-loading battery trays make it easy to swap batteries without removing the optic and Lock Mode prevents accidental adjustments while carrying.

Clarity is a major advantage of Holosun optics. Their multilayer coated glass reduces glare and improves light transmission, giving you a crisp and sharp reticle. This makes aiming more natural and precise in any setting.
Features to Look for in the Best Holosun Optic for Glock 43X MOS
Compact Size and Low Profile
The Glock 43X MOS is slim and built for carry, so the optic must match that profile. A compact sight ensures the pistol stays easy to conceal and avoids unnecessary bulk. Many Holosun models sit low enough to co-witness with standard iron sights, which is ideal for everyday carry.
Long Battery Life
A reliable optic should not drain power quickly. Holosun optics are known for offering up to 50,000 hours of battery life. Many also feature a side-mounted battery tray that allows for quick replacement without removing the sight.

Lighting conditions change and your optic should adapt. Holosun models offer multiple brightness settings, including night vision compatibility. Some also include a multi-reticle system that lets you switch between a dot, a circle or a dot-circle combo for flexibility.
Durable Housing
Your carry pistol optic needs to withstand constant use. Holosun builds many models with 7075 aluminum housings that resist recoil and tough environments. Some even come with enclosed emitters to block dust and water, giving you extra reliability.
Shake Awake and Lock Mode
Holosun’s Shake Awake technology helps save power by turning the dot off when idle and reactivating it with motion. Lock Mode is equally useful, keeping buttons from being pressed by accident while carrying. Both features ensure the sight is ready when needed.
Clear Glass and Coatings
Optical clarity can make all the difference in accuracy. Holosun lenses use multilayer coatings to improve light transmission and reduce glare. This gives you a sharp reticle and a clear sight picture, whether at the range or in self-defense.
