Ameriglo Tritium 2-Dot Rear Handgun Sight for Glock 42/43/43x/48 Green with White Front

The Ameriglo Tritium 2-Dot Rear Handgun Sight for Glock 42/43/43x/48 Green with White Front provides a critical low-light sighting solution for users of Glock’s slimline series. Designed for high-stress environments, this rear sight ensures rapid target acquisition when ambient light is insufficient to see standard iron sights. Whether you are a concealed carry permit holder or an off-duty officer, these sights address the reality that most defensive encounters occur in low-light conditions. This specific configuration is optimized for the subcompact frames of the G42 and G43 families, maintaining a snag-free profile for daily carry.

This rear sight utilizes premium Swiss-made tritium lamps to provide a consistent green glow without the need for batteries or external light charging. The 2-dot configuration features white outlines around the tritium vials, creating a high-contrast visual reference during daytime operations while transitioning to glowing dots in the dark. With a notch width of .165 inches and a height of .256 inches, the sight geometry is engineered to balance speed and precision for the short sight radius of slimline pistols. The rugged steel construction and durable finish ensure the component withstands the friction of holster draws and the harsh vibrations of repetitive recoil.

Professional installation is recommended to ensure proper windage alignment on your Glock 42, 43, 43X, or 48. These sights are an essential upgrade for anyone looking to buy reliable night sights that offer a clear sight picture when paired with a matching front post. Tactical professionals value the AmeriGlo GL-8430R for its proven reliability and its ability to maintain a clear sight picture in diverse lighting environments. Check the specifications for compatibility details before finalizing your purchase to ensure a perfect fit for your specific Glock model.
