The TruGlo Tritium Pro Night Sight Set (TruGlo part number TG231W1W) keeps a defensive handgun visible long after the lights go out. TruGlo builds this square front, U-notch rear set with genuine Swiss tritium, so the dots glow green in low light without batteries or a charging light source. The front sight carries a white outline for a crisp daylight sight picture, while the FOCUSLOCK ring pulls the eye to the front dot faster under stress. Assembled in the USA and fit to most standard holsters, it is a straightforward upgrade for concealed carry and duty pistols that still use factory sight dovetails.

Key Specifications

• This is a Front/Rear Set, giving a matched sight picture instead of pairing a factory rear with an aftermarket front.
• The configuration is a Square Front/U-Notch Rear style, a proven combination for fast sight alignment under recoil.
• Genuine Swiss tritium powers the glow, so the dots stay visible in low light without batteries or a separate charging step.
• A FOCUSLOCK ring around the front tritium vial pulls the shooter’s eye to the front sight faster for quicker follow-up shots.
• The front sight uses a white outline around the tritium vial for a sharp, high-contrast daylight sight picture.
• Sights are assembled in the USA, with final fitment checked against the source pistol’s dovetail specs.

Frequently Asked Questions

Do these sights need batteries? No, the tritium vials glow continuously from radioactive decay and never need batteries or a light source to charge.

Will these fit my holster? TruGlo designed the Tritium Pro profile to fit most standard holsters without requiring a holster swap.

What makes the FOCUSLOCK ring useful? It frames the front tritium vial so your eye locks onto the front sight faster, which speeds up target acquisition in a defensive scenario.
