Hiviz FastDot H3 Sight Set for Glock MOS Red Fiber Optic Front / Green Tritium Rear

The Hiviz FastDot H3 sight set is purpose-built for Glock MOS pistols and pairs a high-visibility red fiber optic front sight with a green tritium rear sight. The combination of bright fiber optic daylight pickup and always-on tritium illumination gives shooters a fast, contrasting aiming picture in bright sun, indoor ranges, and low-light conditions alike - all without batteries for true 24/7 visibility.

This set is compatible with all generations of Glock MOS models chambered in 9mm, .40 S&W, and .357 SIG. Built around a rugged steel body finished in black, the FastDot H3 keeps a low-profile silhouette and is cut to factory sight height so it drops into standard holsters cut for the host pistol without hang-ups.

Designed for shooters who want a single dovetail-fit upgrade that delivers 24/7 visibility, the FastDot H3 installs directly onto the factory rear dovetail and front sight post of Glock MOS pistols. The red fiber optic front gathers ambient light for a crisp aiming point during the day, while the green tritium lamps in the rear take over as light fades, keeping your front-to-rear sight picture fast and intuitive at any hour.
