Holosun optics are built to stay slim on the Glock 43X MOS. Their low profile makes concealed carry comfortable while keeping the pistol easy to handle. You get a sight that adds accuracy without extra bulk.
Strong Aluminum Housing
Most Holosun sights use 7075 T6 aluminum. This material is light but very tough. It resists scratches, recoil and daily wear, so the optic stays reliable even with heavy use.
Extended Battery Life
Holosun’s Super LED technology provides up to 50,000 hours of use. Side-loading battery trays make changes quick and simple. Features like Shake Awake and Solar Failsafe save power, keeping your optic ready longer.

Clear Brightness Control
Holosun sights include multiple brightness settings, with daylight and night-vision levels. The reticle stays visible in bright sun or dim light. That means consistent performance indoors and outdoors.
Reliability in All Conditions
Multi-coated lenses and enclosed emitters on some models keep out dust, moisture and glare. Even in rain or wind, you get a clear view of your target. Glock 43X MOS users can trust the sight in changing environments.

Side Battery Tray
Changing the battery is simple with the side-loading tray. You can swap batteries without removing the sight from the slide. This saves time and keeps your zero intact.
