Trijicon Bright & Tough Night Sights Green Tritium Colt 1911

The Trijicon 600145 Bright & Tough Night Sights deliver superior low-light target acquisition for Colt 1911 pistols with their self-illuminating tritium inserts. These three-dot sights feature green tritium lamps with white outline rings that provide consistent sight picture in all lighting conditions without requiring batteries or external light sources.

What Makes This Different

Unlike standard iron sights that become invisible in darkness, these tritium night sights maintain their glow for over 12 years through radioactive decay. The white outline rings enhance daylight visibility while the green tritium provides 24-hour illumination. Each sight lamp contains gaseous tritium sealed in borosilicate glass capsules that resist impact and temperature extremes from -65°F to +160°F.

Key Features

• Green tritium lamps provide 12+ year illumination without batteries
• White outline rings enhance contrast in bright daylight conditions
• Three-dot configuration for fast sight alignment and target acquisition
• Machined steel construction with protective tritium lamp housing
• Fits Colt 1911 pistols with 0.055" tang rear sight cuts
• Self-luminous operation requires no external power source
• Shock-resistant design withstands slide cycling and recoil forces

These sights excel in tactical applications where split-second target identification matters most. Law enforcement officers rely on the consistent sight picture during low-light encounters, while competitive shooters appreciate the enhanced visibility during dawn and dusk matches. The tritium illumination remains clearly visible in complete darkness yet doesn't overwhelm night vision like electronic sights.
