TRUGLO TFX PRO Tritium Fiber-Optic Night Sights – Glock 42

The TRUGLO TFX PRO combines tritium night sight technology with fiber-optic daylight brightness for 24-hour visibility. These replacement iron sights feature a glowing focus-lock ring front sight for fast target acquisition in any light condition, plus a U-notch rear with a contrasting orange ring. The front sight is encased in a protected TFO capsule that houses both tritium vials and a fiber-optic rod, providing consistent visibility from dawn to dark.

Precision CNC-machined from steel, these sights are designed as a direct drop-in replacement for factory Glock 42 sights. Installation requires a sight pusher tool or professional fitting. The rear sight features an angled edge for emergency one-handed slide racking. The tritium inserts are Swiss-made with a rated lifespan of 12+ years, and the fiber-optic rods gather ambient light during the day for maximum brightness without batteries.
