The TruGlo TG231G1A Tritium night sights deliver reliable low-light target acquisition for Glock 42, 43, 43X, and 48 pistols. These self-illuminating sights maintain consistent visibility in complete darkness without batteries or external light sources. The fortress frame construction provides enhanced durability against daily carry wear and impact.
What Makes This Different
Unlike standard plastic sights or basic luminous dots, these tritium inserts generate their own light through radioactive decay for 12+ years of consistent brightness. The black nitride fortress frame resists corrosion and impact damage better than standard sight housings. Green tritium provides optimal contrast against most backgrounds and lighting conditions compared to other tritium colors.
Key Features
- Self-illuminating green tritium inserts require no batteries or charging
 
- Black nitride fortress frame construction for enhanced durability
 
- Front post and rear dovetail mounting system for secure installation
 
- Compatible with Glock 42, 43, 43X, and 48 (excludes MOS variants)
 
- 12+ year tritium lifespan with consistent brightness output
 
- Green tritium color optimized for human eye sensitivity
 
- Professional installation recommended for proper sight alignment
 
These sights excel in low-light defensive scenarios where split-second target identification matters. The tritium maintains visibility in complete darkness, dawn, dusk, and shadowed environments where standard sights become ineffective. Law enforcement and concealed carry users benefit from the consistent sight picture regardless of ambient lighting conditions. The fortress frame withstands holster wear and environmental exposure during extended carry periods.
