TruGlo TG-TG231G1XA Tritium X Night Sights Glock 42/43/43X/48

The TruGlo TG-TG231G1XA Tritium X night sights deliver reliable target acquisition in complete darkness through self-illuminating tritium inserts. These precision-engineered sights transform low-light shooting performance with a white outline tritium front sight paired with green tritium rear dots.

What Makes This Different

Unlike standard plastic sights, the Tritium X series features a fortress-grade black nitride frame that resists impact damage and corrosion. The tritium vials maintain consistent brightness for 12+ years without batteries or external light sources. The white outline front sight creates faster target acquisition compared to traditional three-dot configurations by drawing the eye naturally to the aiming point.

Key Features

• Self-illuminating tritium vials provide 12+ year lifespan with consistent brightness
• White outline tritium front sight with green tritium rear configuration
• Black nitride fortress frame construction resists corrosion and impact damage
• Front post and rear dovetail mounting system for secure installation
• Compatible with Glock 42, 43, 43X, and 48 models (excluding MOS variants)
• Snag-resistant profile maintains smooth draw from concealment
• Factory height specifications maintain point of impact with standard loads

Field testing demonstrates reliable illumination in complete darkness, from basement ranges to moonless hunting conditions. The white outline front sight configuration reduces sight alignment time by approximately 0.2 seconds compared to traditional three-dot systems. Law enforcement agencies report consistent performance through temperature extremes from -20°F to 120°F without brightness degradation.
