XS Sights DXT2 Big Dot Night Sights for Glock 42/43/43X/48 - Green Tritium Yellow Outline Front / Black Rear

The XS Sights DXT2 Big Dot Night Sights are defensive tritium night sights designed to enhance everyday-carry pistols and optimize target acquisition in self-defense situations. This front and rear sight set is engineered for direct fit on Glock 42, 43, 43X, and 48 handguns, delivering a high-contrast, easy-to-see aiming reference in any lighting condition.

The front sight features XS Sights' signature Big Dot configuration, centered on a green tritium insert surrounded by a yellow photoluminescent outline. The glow dot absorbs ambient light and remains visible in transitional low-light conditions before the tritium becomes readable, while the tritium itself continues to illuminate the front sight through full darkness. The rear sight uses a low-profile V configuration with an i-Dot center reference on a black steel frame, providing a clean sight picture with maximum visibility of the front dot.

Both front and rear inserts are self-illuminating tritium, requiring no batteries or external light source to function. The steel sight bodies are built for durability under hard use and dimensioned for direct slide-fit installation on the slim Glock 42/43/43X/48 platform. Whether carried as a daily conceal pistol or staged as a home-defense gun, the DXT2 Big Dot configuration gives the shooter a fast, daylight-bright sight picture that translates directly to confident, instinctive aiming at the range, in the dark, or in a high-stress defensive encounter.
