Ameriglo GL431 Classic Tritium Sight Set for Glock 42/43/43X/48 - Green Front / Yellow Rear

The Ameriglo GL431 is a Classic Tritium 3-dot night sight set designed for slim-frame Glock 42, 43, 43X, and 48 pistols, including MOS-equipped slides. The set drops into the factory dovetails and gives your carry Glock fast, intuitive aiming in low light without any battery or external illumination.

A green tritium lamp with a white outline sits in the front sight, while the rear carries two yellow tritium lamps with white outlines. The contrasting front-to-rear color scheme is the original Classic 3-dot arrangement trusted by personal defense, military, and law enforcement users. Tritium keeps the inserts glowing around the clock, and the white outlines sharpen the sight picture in daylight.

The steel sight bodies wear a durable black finish and install with standard sight-pushing tools on compatible factory slides, requiring no permanent modification. Whether you carry a G43 every day or run a G48 at the range, the GL431 is a direct, low-profile upgrade over factory iron sights for any subcompact or slim-line Glock pistol in the 42/43/43X/48 family.
