TruGlo TG131G2 Fiber Optic Sight Set Red/Green Glock 20/21

The TruGlo TG131G2 transforms target acquisition speed and accuracy with its contrasting red front and green rear fiber optic configuration. This sight set addresses the common challenge of quick sight alignment in varying light conditions while maintaining the reliability Glock owners demand.

What Makes This Different

Unlike standard three-dot sights, the TG131G2 uses contrasting fiber optic colors that create instant visual separation between front and rear elements. The red front sight naturally draws the eye while the green rear provides clear reference points without distraction. Fiber optic technology gathers ambient light to create bright, glowing sight pictures that outperform tritium in daylight conditions and remain visible in low light scenarios.

Key Features

• Red fiber optic front sight with protective steel ring for maximum visibility
• Green fiber optic rear sight with dual light-gathering rods
• CNC-machined steel construction with corrosion-resistant coating
• Drop-in installation compatible with factory Glock sight cuts
• Snag-resistant profile maintains holster compatibility
• Replaceable fiber optic rods for long-term serviceability
• Contrast color system reduces sight alignment time by up to 30%

Range testing demonstrates superior performance in bright sunlight where tritium sights fade and standard iron sights lack contrast. The fiber optic elements maintain brightness throughout extended shooting sessions without battery dependence. Competition shooters report faster target transitions, while duty officers appreciate the enhanced visibility during daylight operations. The sight set maintains zero through thousands of rounds while withstanding drops and impacts typical of service use.
