TruGlo TFX TG13MP1A Night Sights - Green Tritium Fiber Optic

The TruGlo TFX TG13MP1A combines tritium and fiber optic technology to deliver consistent sight visibility across all lighting conditions. This dual-illumination system automatically transitions from fiber optic brightness in daylight to tritium glow in complete darkness, eliminating the need to switch between different sight systems.

What Makes This Different

Unlike traditional night sights that rely solely on tritium or standard fiber optic sights limited to daylight use, the TFX series integrates both technologies into a single sight set. The hermetically sealed capsule protects both the tritium vial and fiber optic elements from moisture, chemicals, and impact damage. Swiss tritium provides consistent illumination for 12+ years while the fiber optic elements gather ambient light during daylight hours.

Key Features

• Dual-illumination system combines green tritium with fiber optic technology
• White focus lock ring on front sight enhances target acquisition speed
• Hermetically sealed construction protects against moisture and chemical exposure
• CNC-machined steel construction with nitride hardening treatment
• Snag-resistant design with rounded edges for smooth draw
• Compatible with most holsters designed for factory sight profiles
• Swiss tritium rated for 12+ year lifespan with consistent brightness

Field performance remains consistent across temperature extremes from -20°F to 120°F. The sight picture maintains clarity in rain, snow, and high-humidity environments due to the sealed capsule design. Competition shooters benefit from the rapid target acquisition provided by the contrasting white outline, while the tritium ensures reliable performance during low-light defensive scenarios.
