TruGlo TG231N2 Tritium Night Sights - Green Front/Rear Black

The TruGlo TG231N2 Tritium Night Sights deliver reliable low-light target acquisition with self-illuminating tritium inserts that require no batteries or external light source. These precision-machined steel sights feature bright green tritium vials housed in protective steel bodies for dependable performance in complete darkness.

What Makes This Different

Unlike fiber optic sights that depend on ambient light, tritium night sights generate their own illumination through radioactive decay, maintaining consistent brightness for over 12 years. The TG231N2 features matched green tritium inserts in both front and rear sights, creating uniform sight picture alignment. Steel construction withstands repeated impacts and harsh conditions that would damage polymer alternatives.

Key Features

• Self-luminous green tritium inserts provide 12+ year lifespan without batteries
• CNC-machined steel construction with black oxide finish resists corrosion
• Standard dovetail mounting fits most factory sight cuts
• White outline rings enhance daylight visibility and sight alignment
• Low-profile design prevents snagging on clothing or holsters
• Matched front and rear tritium color eliminates confusion in low light
• Professional installation recommended for proper zero retention

These night sights excel in home defense scenarios where room clearing or early morning response requires instant target identification. Law enforcement officers appreciate the consistent illumination during shift work, while competitive shooters benefit from the precise sight picture in indoor ranges. The tritium maintains brightness in temperatures from -40°F to 160°F, ensuring reliable function across all climates.
