HiViz FastDot H3 Sight Set for Glock MOS 9mm/.40 S&W/.357 Sig

The HiViz FastDot H3 is an iron sight set for Glock MOS pistols chambered in 9mm Luger, .40 S&W and .357 Sig. It pairs a red fiber optic front sight with a green tritium rear sight, giving a high-contrast dot in daylight and a self-illuminating reference when light fades. The single low-profile dot design is intended to avoid snagging on the draw while still providing a clear aiming reference.

The sights are machined from steel, which the listing describes as more resistant to wear from repeated holstering and daily carry than polymer. The fiber optic front requires no batteries, and the tritium rear is rated by the manufacturer to remain visible for roughly 12 years. The front post mounts directly and the rear seats in a standard dovetail. The set is intended for Glock MOS slides cut for standard sights.
