Meprolight Hyper-Bright Tritium Night Sights Glock 42/43 Green/Yellow

The Meprolight USA 402203121 Hyper-Bright tritium sight set transforms low-light shooting accuracy for Glock 42 and 43 pistols. This professional-grade sight system combines self-illuminated tritium technology with high-contrast outline colors for rapid target acquisition in any lighting condition. The enhanced brightness delivers consistent performance without batteries or external light sources.

What Makes This Different

Meprolight's Hyper-Bright technology produces 30% more illumination than standard tritium sights through advanced gas-filled capsule design. The front sight features green tritium with a bright yellow outline for maximum visibility, while the rear sight uses green tritium with a black outline to create proper sight picture contrast. This color combination follows proven three-dot alignment principles used by military and law enforcement agencies worldwide.
