TruGlo TG131GT2Y TFO Black Handgun Sights | Green Tritium Fiber Optic Front & Yellow Tritium Fiber Optic Rear

The TruGlo TG131GT2Y TFO handgun sights combine tritium and fiber-optic technology to deliver a bright, reliable sight picture in any light condition—from bright daylight to total darkness. If you shoot pistols for self-defense, competition, or sport, you know that a fast, confident sight acquisition can mean everything. These black sights pair a green tritium fiber-optic front sight with a yellow tritium fiber-optic rear sight, giving you the speed of fiber-optics when light is available and the glow of tritium when it isn't. No batteries required, no on/off switches—just point and shoot, any time of day or night.

TruGlo's patented dual-technology design means you're not compromising between daylight brightness and low-light visibility. The fiber-optic elements gather ambient light for a vivid sight picture in daylight, while the tritium vials take over in darkness, eliminating the need to rely on batteries or electronic aiming aids. The concealed fiber design keeps the light-gathering elements from being visible downrange, and the snag-resistant design won't catch on clothing or gear when you draw. Built from CNC-machined steel for durability, these sights are engineered to handle hard use.

These are drop-in replacements for standard handgun sight dovetails, and they fit standard holsters without modification. Whether you're training at the range, competing, or carrying for personal protection, TruGlo TFO sights give you the tactical edge of consistent sight visibility without adding weight, complexity, or maintenance.

Specifications

Frequently Asked Questions

Will these TruGlo sights fit my handgun?

These sights are designed for standard handgun sight dovetails. Verify that your pistol has a compatible dovetail mounting system before purchase. TruGlo offers models for a range of common handgun platforms, so check the specific model number to ensure proper fit for your gun.

How do tritium fiber-optic sights work in low light?

The tritium vials are self-illuminating and glow in darkness without requiring batteries or external power. During the day, the fiber-optic elements gather ambient light for extra brightness. As light fades, the tritium takes over, so you maintain sight visibility from dawn to dusk and everywhere in between.

Will these sights work with my existing holster?

Yes, these sights are designed with a snag-resistant profile and fit standard holsters without modification. The sight height and profile are compatible with most OEM and aftermarket holsters.

Are batteries included, or do I need to maintain these sights?

No batteries are required. Tritium is self-illuminating and requires no maintenance or power source. These sights are designed to function reliably for years with zero upkeep beyond normal cleaning.
