TruGlo TG231G1A tritium night sights deliver reliable, low-light visibility for pistol shooters who need to see their sights when it matters most. These green front and rear tritium sights glow in complete darkness without batteries or charging—a straightforward upgrade for defensive shooters, competition runners, and hunters who train or operate in low-light conditions. Built with Swiss tritium for brightness and assembled in the USA, they're engineered to outlast your gun.
The rear sight features a quick-handling U-notch design and an angled edge that lets you achieve sight picture and press rounds downrange even in a one-handed emergency drill. The front sight includes TruGlo's FOCUS-LOCK ring, a feature borrowed from their acclaimed TFX PRO line, letting you lock focus where your eyes naturally settle and acquire target faster. The sights stay snag-free and fit standard holsters—no grinding, filing, or holster swaps required.
Durability is built in: a permanent FORTRESS FINISH protective coating guards against corrosion and handling wear. Because tritium glows on its own, you're never dependent on ambient light or a working light source. Whether you carry for protection, shoot competitions after sunset, or hunt in dim conditions, these sights keep your sight picture bright when it counts.
