Trijicon: Trijicon is a well-known manufacturer of firearms sights, including night sights, red dot sights, and other aiming solutions, known for their quality and durability.
Glk 20/21: These night sights are specifically tailored to fit Glock models 20 and 21. The Glock 20 is a full-size semi-automatic pistol chambered in 10mm Auto, and the Glock 21 is a full-size pistol chambered in .45 ACP.
Suppressor Night Sights (Sup Nite Site): These sights are designed for use with suppressors or silencers attached to the firearm. They are taller than standard sights, ensuring that the sights remain visible and usable when a suppressor is mounted.
White/Green and White/Yellow: These color combinations typically refer to the color of the tritium inserts in the sights. Tritium is a radioactive isotope used in night sights to provide illumination in low-light conditions. "White/Green" indicates that the front sight has a green tritium insert with a white outline, while "White/Yellow" suggests that the rear sight has a yellow tritium insert with a white outline. These contrasting colors help with quick sight alignment in various lighting conditions.
Trijicon night sights are favored for their reliability and visibility in low-light or nighttime scenarios. Tritium ensures that the sights remain illuminated without the need for external light sources.
