Meprolight Tru-Dot Green Tritium Night Sights for Glock 42

The Meprolight Tru-Dot Green Tritium Night Sights transform target acquisition in low-light conditions for Glock 42 pistols. Self-illuminated tritium inserts provide instant sight picture without batteries or external light sources, giving shooters a critical advantage during dawn, dusk, and nighttime scenarios.

What Makes This Different

Unlike painted dots or fiber optic sights that require ambient light, these tritium sights generate their own illumination through radioactive decay. The green tritium vials maintain consistent brightness for over 12 years, while the contrasting black rear frame creates clear sight alignment. Military and law enforcement agencies worldwide rely on Meprolight's tritium technology for mission-critical applications.

Key Features

• Self-luminous green tritium vials provide 12+ year lifespan without batteries
• Black rear sight frame enhances contrast and reduces glare
• Precision-machined steel construction withstands heavy recoil and impacts
• Drop-in replacement for factory Glock 42 sights
• Three-dot configuration for intuitive sight alignment
• Corrosion-resistant finish maintains performance in harsh conditions
• Israeli military specifications ensure battlefield reliability

These sights excel in home defense scenarios where room clearing requires rapid target identification. Competition shooters benefit from consistent sight picture during early morning matches, while concealed carriers gain confidence knowing their backup pistol remains effective regardless of lighting conditions. The tritium maintains brightness in temperatures from -40°F to 160°F.
