TruGlo TG231W2W Tritium Pro Black Sights | Green Tritium Front & Rear with White Outline

The TruGlo TG231W2W Tritium Pro Black Sights deliver glow-in-the-dark aiming when it matters most—no batteries, no light source needed. These green tritium night sights pair Swiss tritium tubes with a clean white outline on the rear aperture, giving you a sharp sight picture in daylight and an unfailing glow in darkness or low-light shooting. Built for shooters who demand reliability in any condition, these sights are assembled in the USA and finished with a protective FORTRESS coating to resist corrosion and abuse. The design is snag-resistant and fits standard holsters, making them a drop-in upgrade for everyday carry or duty weapons.

What sets the Tritium Pro apart is the combination of speed and precision. The front sight features a FOCUS-LOCK ring to help your eye lock onto the target faster, while the U-notch rear aperture is quick to aim and easy to use under stress. The rear sight's angled edge means you can rack the gun one-handed against a belt, boot, or obstacle if your support hand is compromised—a real asset in a fight.

Swiss tritium is brighter and more durable than standard night-sight material, and these sights are designed to hold that glow for years of reliable service. Whether you're training in low light, shooting at dusk, or depending on your pistol in a worst-case scenario, tritium sights give you an aiming reference when your flashlight or daylight sights won't. The black finish is low-profile and won't catch unwanted light, and the white outline rear sight helps you align quickly even when the tritium tubes are fresh and very bright.

Frequently Asked Questions

What do tritium night sights look like in daylight?

The TruGlo Tritium Pro sights feature a white outline on the rear aperture and green tritium tubes front and rear. In daylight, the white rear outline pairs with the front tritium tube to give you a conventional sight picture. The tritium glow is faint in bright light but becomes increasingly visible as ambient light drops.

Will these sights work if the tritium goes dim?

These sights are designed with the white outline rear aperture and green front tube so you maintain a usable sight picture even if the tritium loses brightness over time. The combination of the outline and the tube ensures you're not entirely dependent on the glow alone.

Can I use these sights for one-handed shooting or racking?

Yes. The rear sight features an angled edge specifically designed for emergency one-hand operation, allowing you to rack the slide against your belt, boot, or another object if your support hand is injured or occupied.

What finish do these sights have, and will they rust?

The sights are finished in black with a FORTRESS protective coating designed to provide maximum protection against corrosion and wear. This coating helps them resist rust and damage from handling and environmental exposure.
