TruGlo TFO Tritium & Fiber Optic Handgun Sights - Green Front, Yellow Rear (TGTG131NT1Y)

The TruGlo TFO Tritium & Fiber Optic Handgun Sights combine two proven light-gathering technologies in one handgun sight set, delivering a bright, reliable sight picture whether you're shooting in bright daylight, dim indoor ranges, or complete darkness. The green front sight and yellow rear sight give you excellent contrast and quick target acquisition across any lighting condition—no batteries required, no waiting for your eyes to adjust.

What makes the TFO different is its hybrid design: fiber-optic elements gather ambient light to keep the front sight brilliantly visible in daylight and low-light conditions, while tritium vials provide constant glow when light fades entirely. You get the speed and brightness advantage of fiber optics when you need it, and the always-on tritium backup when darkness falls. This approach eliminates the dead zone many single-technology sights suffer at dusk or in shadowy indoor environments.

Built from CNC-machined steel, these sights are rugged enough for duty carry, sport shooting, or defensive training. The snag-resistant design won't catch on clothing or holster, and they work with standard holsters designed for conventional iron sights. The concealed fiber construction means your target won't see a glowing front sight—you get the aiming advantage without telegraphing your position.

TruGlo's TFO sights are a solid choice for shooters who want to upgrade their factory iron sights and can't afford downtime wondering if their sights will work when light is low. Whether you're training daily, carrying a defensive pistol, or hunting in changing conditions, a reliable sight picture matters.

Frequently Asked Questions

Will TruGlo TFO sights work on my handgun?

TruGlo TFO sights are designed to fit standard 3-dot sight dovetails and work with standard holsters. Verify your specific handgun model's compatibility with your supplier or gunsmith before ordering, as installation may require gunsmithing on some platforms.

How do these sights work in low light and complete darkness?

The fiber-optic elements gather available light to keep the front sight bright in daylight and dusk. The tritium vials are self-illuminating and glow constantly in darkness without any external power source, providing a visible sight picture when ambient light disappears entirely.

Do I need to replace batteries or recharge these sights?

No. Fiber optics are passive and require no power. Tritium is a radioactive isotope that self-illuminates without batteries or charging, though tritium sights eventually dim over many years as the isotope decays.

What's the difference between these and single-tech night sights or fiber-optic sights?

Single-technology sights (tritium-only or fiber-optic-only) each have a weakness: tritium alone is invisible in bright daylight, and fiber optics alone go dark after sundown. The TFO combines both, giving you fast, bright aiming in daylight and a glowing sight picture at night.
