Meprolight Hyper-Bright Tritium Sight Set Glock 42/43 Green/Orange

The Meprolight USA 402203131 Hyper-Bright tritium sight set delivers enhanced target acquisition for Glock 42 and 43 pistols through advanced self-illuminated technology. This professional-grade sight system combines green tritium inserts with high-contrast colored outlines for superior visibility in all lighting conditions.

What Makes This Different

The Hyper-Bright tritium technology produces significantly more light output than standard tritium sights, maintaining consistent brightness for over 12 years. The front sight features a vibrant orange outline surrounding the green tritium insert, while the rear sight utilizes a subdued black outline to eliminate visual confusion. This color contrast system allows faster sight alignment compared to traditional three-dot configurations or basic tritium installations.

Key Features

• Self-illuminated green tritium inserts maintain brightness for 12+ years without batteries
• Orange outline front sight with black outline rear sight for rapid target acquisition
• Hyper-Bright tritium technology delivers enhanced light output over standard tritium
• Precision machined steel construction with corrosion-resistant finish
• Drop-in installation compatible with Glock 42 and Glock 43 factory sight cuts
• Low-profile design maintains holster compatibility with most retention systems
• Snag-resistant rear sight profile for concealed carry applications

The tritium inserts provide reliable illumination during low-light engagements, dawn/dusk transitions, and indoor scenarios where standard sights become difficult to acquire. The contrasting color system proves particularly effective for competitive shooting, where split-second sight alignment determines match outcomes. Weather-sealed tritium capsules maintain performance through temperature extremes and moisture exposure typical in duty or outdoor use.
