Trijicon Night Sights for Glock 20/21 – Tritium 3-Dot System

Trijicon night sights deliver self-luminous tritium illumination for reliable target acquisition in low-light and no-light conditions. The 3-dot configuration provides intuitive sight alignment without batteries or external power sources. Tritium lamps are hermetically sealed and rated for 12+ years of continuous illumination, making these sights a long-term defensive sight solution for Glock 20 and 21 pistols.

Designed as a drop-in replacement for factory Glock sights, these night sights install using standard sight tools and fit standard holsters. The front sight features a white outline around the tritium insert for enhanced visibility in daylight, while the rear sight features two tritium dots. Machined steel construction with a matte black finish ensures durability and reduces glare.
