TruGlo TG13FN1A TFX Night Sights - FN Pistol Green Tritium

The TruGlo TG13FN1A TFX night sights deliver 24-hour visibility with a dual-illumination system that combines tritium vials with fiber optic technology. This sight set transforms low-light shooting performance for FN pistol owners seeking professional-grade accuracy in all conditions.

What Makes This Different

The TFX series stands apart from standard night sights through its patented dual-illumination design that captures ambient light during the day while relying on tritium gas for nighttime visibility. The white outline front sight provides faster target acquisition compared to plain black sights, while the compact profile maintains holster compatibility. Swiss tritium vials maintain consistent brightness for 12 years without batteries or external power sources.

Key Features

• Dual-illumination system combines green tritium with fiber optic light gathering
• White outline front sight with green tritium center dot for enhanced contrast
• Machined steel construction with protective TFX coating resists impacts
• Factory-specific fitment for FN pistol models ensures proper installation
• Sealed tritium vials rated for 12-year illumination lifespan
• Low-profile design maintains compatibility with existing holsters
• Front sight measures 0.140" width for precise sight picture

Field testing demonstrates reliable performance across temperature extremes from -20°F to 160°F without sight shift or illumination degradation. The fiber optic elements automatically adjust to available light conditions, providing bright sight pictures in daylight while the tritium maintains visibility in complete darkness. Law enforcement and competitive shooters report improved first-shot accuracy during low-light engagements and faster target transitions in dynamic shooting scenarios.
