TruGlo TG13GL3A TFX Green Tritium Night Sights for Glock Pistols

The TruGlo TG13GL3A TFX sight set combines fiber optic brightness with tritium reliability for 24-hour target acquisition on Glock pistols. This dual-illumination system maintains consistent sight picture from bright daylight through complete darkness.

What Makes This Different

The TFX series integrates fiber optic rods with tritium gas tubes in a single sight body, eliminating the need to choose between day and night visibility. While standard tritium sights fade in bright light and basic fiber optics disappear in darkness, this hybrid design automatically adjusts brightness based on ambient light conditions. The patented capsule design protects both illumination sources from impact damage.

Key Features

• Dual-illumination technology with fiber optic and tritium for 24-hour visibility
• Green front and rear dots for consistent sight alignment
• Black nitride Fortress frame construction resists corrosion and wear
• Post mount installation compatible with factory Glock dovetails
• Fits most Glock models excluding MOS (Modular Optic System) variants
• Snag-resistant profile with rounded edges for concealed carry
• Swiss tritium rated for 12-year lifespan

Field performance remains consistent across temperature ranges and lighting conditions. The green illumination provides faster target acquisition than traditional white dots, particularly beneficial for law enforcement and competitive shooting applications. The sight picture maintains clarity in rain, snow, and humid conditions due to the sealed capsule construction.
