Meprolight Tru-Dot Night Sight Set - Glock 9mm .357 Sig 40 S&W .45 GAP Fixed Set Green/Orange

The Meprolight Tru-Dot Night Sight Set for Glock 9mm, .357 Sig, .40 S&W, and .45 GAP delivers self-illuminating, fixed tritium night sights optimized for rapid target acquisition in low-light conditions. This fixed sight set pairs a green front post with an orange rear post, creating a high-contrast sight picture that remains effective across variable lighting environments without requiring battery power or external illumination.

Meprolight's tritium-based illumination system uses self-luminous isotope technology to provide continuous visibility in darkness, a standard proven across decades of law enforcement and military deployment. The green-over-orange configuration—bright front sight over darker rear sight—follows precision shooting doctrine and enables faster sight alignment under stress. The fixed sight design eliminates adjustment concerns after installation; once zeroed, the sight picture remains consistent through the service life of the tritium vial, typically 10–12 years. Compatibility spans the full range of Glock platforms across those four caliber families, making this set suitable for standard duty guns, training pistols, or backup firearms.

This sight set addresses the requirements of patrol officers, armed security personnel, competitive shooters, and civilian self-defense practitioners who operate in low-light venues or conduct night-shift duties. The non-adjustable fixed sight format removes the complication of elevation or windage tuning during a duty cycle, prioritizing reliability and shot placement consistency over fine-tuning capability. Operators carrying duty guns through varied lighting—from brightly lit indoor facilities to outdoor night operations—benefit from tritium night sights that function passively, independent of flashlight availability or tactical light batteries.

Meprolight remains a recognized manufacturer of tritium-illuminated sighting systems across military, law enforcement, and civilian markets since 1990, with combat-proven products deployed by armed forces worldwide. The Tru-Dot line represents the company's foundational night sight offering—a direct-fit alternative to factory Glock sights for users prioritizing low-light target identification without electronic dependency.
