TRUGLO BRITE-SITE TFO for Glock 42/43 – Tritium Fiber-Optic Pistol Sights

The TRUGLO BRITE-SITE TFO combines tritium night sight illumination with fiber-optic daylight brightness in a single sight system for Glock 42 and 43 pistols. Tritium vials provide a constant glow in low-light or complete darkness, while fiber-optic rods gather ambient light for a bright sight picture in daylight conditions. The green front sight and green rear dots create a fast three-dot alignment system for quick target acquisition across all lighting conditions.

Designed as a direct replacement for factory Glock sights on G42 and G43 models, these sights install using a standard sight pusher or drift punch for the rear and a sight press or professional installation for the front. CNC-machined steel construction with a snag-resistant profile ensures durability without interfering with holster draw. The TFO technology eliminates the need to choose between tritium night sights and fiber-optic day sights—both functions are integrated into a single, self-illuminating sight set.
