The TruGlo TG131XTY TFO night sight set pairs a black front sight with green tritium and fiber optic with a rear sight featuring yellow tritium and fiber optic. It's built on TruGlo's patented dual-technology platform that combines fiber optic brightness for daylight shooting with tritium glow for low-light and darkness use. If your handgun needs to work equally well on the range in bright sun or on a defensive draw in complete darkness, this sight set gives you reliable target acquisition across all lighting conditions without batteries or external power.
The fiber optic channels gather ambient light and deliver a vivid sight picture when the sun is up—especially in the green front sight. When darkness falls, the tritium elements take over, providing a self-illuminating glow that needs no charging or maintenance. The yellow rear sight is intentionally less bright than the front, designed to create contrast and help your eye naturally align the sights. CNC-machined steel construction means these sights are built to handle hard use and rough handling without going out of zero.
The snag-resistant design won't hang on clothing or holster during a draw, and the sights fit standard holsters so you won't need to buy new leather. The fiber optics are concealed within the sight body, so they won't give away your position to a target downrange. No batteries, no charging, no complicated setup—just install and go.

| Model Number | TG131XTY |
| Front Sight | Black with green tritium and fiber optic |
| Rear Sight | Black with yellow tritium and fiber optic |
| Construction | CNC-machined steel |
| Technology | Patented TFO (tritium and fiber optic combination) |
| Power Source | None required—self-illuminating tritium and passive fiber optic |
These are standard dovetail sights designed to fit handguns with conventional sight slots. Verify your handgun's sight system before purchasing to confirm compatibility.
In daylight and bright conditions, the green and yellow fiber optic channels capture ambient light and glow brightly, giving you a vivid sight picture. In darkness or low light, the tritium elements self-illuminate, providing a reliable glow with no batteries or charging required. The technology transitions automatically depending on available light.
Yes. The tritium elements glow in complete darkness without any external light source or battery. The fiber optic will not glow in total darkness, but the tritium alone provides a usable sight picture.
The yellow rear sight is intentionally less bright than the green front sight to create visual contrast and help your eye naturally align the three-dot sight picture more quickly and accurately.
