The TruGlo TG13RS3A TFXBlack tritium and fiber optic sights combine two proven lighting technologies to keep your front and rear sights visible in any condition—bright sunlight, low light, or complete darkness. This set pairs green tritium elements (which glow 24/7 without batteries) with an exposed fiber optic channel on the front sight, ensuring you can acquire a fast, confident sight picture whether you're on the range at noon or hunting in dim timber. The white outline ring around the front sight helps your eye snap to the front post naturally, the fundamentals that make accurate shooting automatic.
Built on a snag-resistant, compact design that works with standard holsters, these sights are engineered for durability in field conditions. The illuminating elements sit inside a sealed, chemical and shock-resistant capsule—protected from solvents, oils, and ultrasonic cleaning. The CNC-machined steel frame is coated with TruGlo's FORTRESS FINISH, a rust-proof protective layer designed to handle hard use and tough environments.
Whether you're setting up a carry gun, a patrol rifle, or a range gun that sees frequent use, the TFXBlack sights deliver the real-world advantage of visible aiming points in any light—no fumbling, no guessing. Swiss-quality tritium and bright fiber optic technology have earned their reputation for reliability, and this pairing gives you the best of both worlds in a compact, snag-free package.
| Brand | TruGlo |
| Model | TG13RS3A TFXBlack |
| Sight Type | Tritium and Fiber Optic (Fixed) |
| Front Sight | Green Tritium with Fiber Optic Channel, White Outline Ring |
| Rear Sight | Green Tritium |
| Construction | CNC-Machined Steel with FORTRESS FINISH |
| Tritium Source | Swiss-quality |

| Power Source | None (Tritium is self-illuminating) |
These TFXBlack sights use a dual-light system. The tritium provides 24/7 self-illumination without batteries, while the fiber optic front channel captures and amplifies available light in daytime conditions. This gives you a bright, visible aiming point across a much wider range of lighting—from bright sun to complete darkness. Standard tritium-only sights rely solely on the glow in darkness, which is dimmer in daylight.
The TG13RS3A is designed to fit standard dovetail sight mounts found on most pistols and rifles. We recommend verifying your firearm's sight mounting system before ordering. If you're unsure about compatibility with your specific gun, reach out to our team and we'll help confirm the fit.
Yes. The tritium and fiber optic elements are fully encapsulated inside a sealed, chemical-resistant capsule that shields them from cleaning solvents, oils, and ultrasonic cleaning processes. The outer steel frame is also treated with a rust-proof FORTRESS FINISH coating for maximum protection against environmental corrosion and wear.
No. The tritium elements glow on their own—they're self-illuminating and require no batteries, power source, or charging. Once installed, they'll continue to glow reliably for years. The robust sealed design also means minimal maintenance; you can clean them with standard gun-cleaning methods without worry.
