TruGlo TFXBlack TG13FN3A Tritium & Fiber Optic Sight Set - Green/White Front, Green Rear

The TruGlo TFXBlack TG13FN3A is a tritium and fiber optic sight set built for shooters who need reliable target acquisition in any light. Combining Swiss tritium technology with protected fiber optics, this sight set delivers the always-on visibility of self-illuminating night sights paired with the daytime brightness of fiber — no batteries required, no switching between setups. The green/white front sight and green rear sight configuration gives you a proven aiming geometry that works whether you're shooting in dim indoor spaces, bright outdoors, or anywhere in between.

The core appeal of TFX sights is that dual-light design: tritium glows continuously for low-light shooting, while fiber optics gather ambient light for a blazing bright sight picture during the day. The fiber is concealed within the sight housing, so it stays protected from damage and doesn't telegraph your position to a target. The whole package is treated with TruGlo's Fortress Finish, a permanent protective coating that resists oils, chemicals, and cleaning solvents — including ultrasonic cleaning processes — so your sights stay as durable as your commitment to training.

These sights are engineered with a snag-resistant design and fit standard holsters, making them a practical upgrade for carry guns, duty weapons, or any defensive or hunting firearm that uses them. TruGlo has built the TFXBlack with rugged construction meant to handle real-world use without fussing.

Frequently Asked Questions

Will these sights work on my pistol if I use a holster?

Yes. TruGlo designed the TFXBlack with a snag-resistant profile that fits standard holsters without snagging or causing compatibility issues.

No. The tritium is self-illuminating and requires no batteries or charging. The fiber optics are completely passive, gathering ambient light during the day.

How do these sights perform in low light or darkness?

The Swiss tritium automatically glows in the dark, giving you a visible sight picture 24/7 without any power source. This makes them ideal for low-light defensive or hunting scenarios.

Are these sights durable if I clean my gun regularly?

Yes. The Fortress Finish protective coating is specifically designed to withstand oils, chemicals, cleaning solvents, and even ultrasonic cleaning processes, so your sights stay protected through your normal maintenance routine.
