Trijicon 600777 Bright & Tough Night Sights Glock 42/43 Green Tritium

The Trijicon 600777 Bright & Tough Night Sights deliver reliable target acquisition in low-light conditions for Glock 42 and 43 pistols. These self-luminous tritium sights eliminate the need for batteries or external light sources while providing precise aiming capability 24/7. Built specifically for small-frame Glock pistols, they maintain the compact profile essential for concealed carry applications.

What Makes This Different

Unlike standard plastic sights or basic luminous paint options, these tritium night sights feature actual radioactive tritium gas sealed in borosilicate glass vials. The green tritium provides consistent brightness for approximately 12 years without degradation from weather exposure or repeated use. White outline rings enhance contrast during daylight shooting, creating a dual-purpose sight system that performs across all lighting conditions.

Key Features

• Self-luminous green tritium inserts provide 12-year lifespan with no battery requirement
• White outline front and rear sights enhance daylight visibility and target contrast
• Machined steel construction withstands recoil and impact damage
• Drop-in replacement for factory Glock 42/43 sights with standard dovetail cuts
• Sealed tritium vials resist moisture, chemicals, and temperature extremes
• Low-profile design maintains holster compatibility and snag-free draw
• Three-dot sight picture provides intuitive sight alignment

Field performance remains consistent across temperature ranges from -65°F to +160°F, making these sights suitable for duty carry, competition shooting, and personal defense scenarios. The tritium brightness automatically adjusts to ambient light conditions, appearing dimmer in daylight and brighter in darkness. Installation requires basic gunsmith tools and sight pusher for proper dovetail fitting.
