The TruGlo TG231F1W Tritium Pro night sights bring low-light performance to your carry or duty pistol with Swiss tritium capsules that glow without batteries or charging. Green tritium on both front and rear, paired with a white outline on the front sight, creates a sight picture that's fast to acquire in dim conditions and easy to track in daylight. Built with a U-notch rear design and front sight FOCUS-LOCK ring for consistent, repeatable focus, these sights are engineered for shooters who need reliable performance when ambient light runs out.

The TG231F1W is assembled in the USA and finished with a durable FORTRESS coating that stands up to holster wear and the elements. The angled rear sight edge lets you rack the slide one-handed if you ever need to, and the snag-resistant profile won't catch on your clothing or gear during the draw. Swiss tritium is used throughout for maximum brightness—no compromise on visibility in complete darkness or low-light shooting scenarios.

These sights fit standard holsters and integrate seamlessly into most carry setups. Whether you're a competitive shooter, law enforcement, or a civilian prioritizing low-light readiness, the Tritium Pro sights deliver the glow-in-the-dark advantage when daylight fades.
