TRUGLO BRITE-SITE TFX Night Sights – Glock 42/43

The TRUGLO BRITE-SITE TFX combines tritium and fiber-optic technology for bright aiming points in any lighting condition. Tritium vials provide a constant glow in darkness, while fiber-optic capsules gather ambient light for enhanced visibility in daylight. These sights are built for defensive handguns where fast target acquisition matters.

Designed specifically for Glock 42 and 43 pistols, the TFX features a compact profile that won't snag on holsters or clothing. The front sight has a white focus ring for quick alignment, while the rear sight is blacked out to reduce visual clutter. CNC-machined steel construction with a Fortress Finish coating resists corrosion and wear. Installation requires a sight pusher tool or gunsmith fitting.
