The TruGlo TG231N1 Tritium Night Sights deliver reliable low-light visibility with self-illuminating tritium inserts that require no batteries or external light sources. These professional-grade sights provide consistent aiming points in complete darkness for up to 12 years.
What Makes This Different
Unlike fiber optic sights that depend on ambient light, tritium sights maintain brightness through radioactive decay, ensuring visibility regardless of lighting conditions. The TG231N1 features Swiss tritium vials rated for continuous illumination, while many budget alternatives use painted dots that fade quickly. Each sight undergoes precision machining to ensure proper sight alignment and maintains zero once installed.
Key Features
- Green tritium inserts in both front and rear sights for consistent sight picture
- Swiss-made tritium vials rated for 12-year continuous illumination
- CNC-machined steel construction with black nitride finish
- Standard height profile maintains existing holster compatibility
- White outline rings enhance daylight visibility and contrast
- Drop-in replacement for factory Glock sights
- Professional installation recommended for proper fit and function
These sights excel in tactical applications where split-second target acquisition matters. Law enforcement professionals rely on tritium sights for duty carry, while competitive shooters appreciate the consistent sight picture in varying light conditions. The green tritium provides optimal contrast against most backgrounds and maintains visibility through rain, fog, and low-light scenarios without compromising daylight accuracy.
