Ameriglo GL351 Protector Sight Set for Glock 42/43/43X/48 - Green Tritium Orange Outline Front / Black Serrated Rear

The Ameriglo GL351 Protector Sight Set is a purpose-built tritium night sight pair designed specifically for the slim-frame Glock 42, 43, 43X, and 48 pistols. Part of Ameriglo's Protector series, this set is engineered to promote quicker front sight acquisition, making it a popular upgrade for concealed carry and personal defense handguns.

The front blade carries a self-illuminating green tritium lamp ringed by a high-visibility orange outline that draws the shooter's eye to the front sight in any lighting condition, with no battery required. The rear sight is a black serrated steel U-notch that reduces glare and naturally directs focus onto the front blade, supporting fast and intuitive sight alignment in low-light and defensive situations.

Both front and rear sights are built on rugged steel housings with a protective black finish, designed for direct slide mounting on compatible Glock 42, 43, 43X, and 48 slides. The compact, snag-resistant profile keeps the GL351 well suited to everyday carry, while the always-on tritium delivers dependable aiming reference in dim environments - ideal for home defense and concealed carry use.
