Ameriglo yellow tritium rear night sight with white outline dots for Glock 42, 43, 43X, and 48. Features .256" height and .165" square notch for reliable low-light shooting.
Ameriglo's tritium night sights represent a proven solution for shooters who demand reliable target acquisition in low-light conditions. This rear sight is specifically engineered for the Glock 42, 43, 43X, and 48 platforms.
Tritium night sights glow continuously through self-luminous technology. Unlike fiber optic or LED solutions, they require no external light source and never need batteries. The white outline dots aid in daylight shooting while the glowing tritium cores activate in darkness, making these sights versatile for any lighting condition.
These sights are ideal for defensive carry, home protection, or anyone who shoots across varying light conditions. Installation requires basic gunsmithing knowledge or professional installation.
