TruGlo TFO TG131GT2Y Night Sights Green/Yellow Glock 20/21

The TruGlo TFO TG131GT2Y combines tritium and fiber optic technology to deliver reliable sight acquisition in any lighting condition. This sight set features a green tritium/fiber optic front sight paired with a yellow tritium/fiber optic rear sight, specifically engineered for Glock 20 and 21 pistols.

What Makes This Different

Unlike standard tritium-only night sights, the TFO (Tritium/Fiber Optic) system utilizes dual illumination sources for maximum visibility. During daylight hours, the fiber optic elements collect ambient light for bright sight pictures, while tritium inserts provide consistent glow in low-light conditions. The contrasting green front and yellow rear configuration creates faster target acquisition compared to same-color sight systems. Each tritium vial maintains brightness for 12+ years without batteries or external light sources.

Key Features

• Dual tritium and fiber optic illumination for 24/7 visibility
• Contrasting green front/yellow rear sight picture for rapid target acquisition
• CNC-machined steel construction with protective sight ring
• Factory-height profile maintains existing holster compatibility
• Snag-resistant design with smooth edges for concealed carry
• Swiss tritium vials rated for 12+ year lifespan
• Drop-in replacement for factory Glock 20/21 sights

The TFO system excels across multiple shooting scenarios, from competitive shooting where split-second sight alignment matters to duty applications requiring consistent performance. The fiber optic elements gather available light during dawn and dusk conditions when standard tritium sights appear dim. Law enforcement and concealed carry users benefit from the snag-free profile that won't catch on clothing or gear during draw cycles.
