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

The XS Sights DXT2 Big Dot Night Sights are defensive tritium night sights purpose-built for concealed-carry Glock pistols. Engineered to fit the Glock 42, 43, 43X, and 48, this front/rear sight set gives shooters a high-contrast aiming reference in any lighting condition.

The DXT2 Big Dot front sight features XS's proprietary photoluminescent Glow Dot surrounding a self-illuminated green tritium lamp. The Glow Dot absorbs ambient light and glows brightly before it is dark enough to see the tritium center, then continues to glow as the tritium takes over, delivering around-the-clock visibility. A bold orange outline ring further enhances daylight contrast for fast target acquisition. The rear sight pairs a wide, V-notched green tritium lamp with a crisp white outline bar, leaving an unobstructed view of the front sight so the shooter's focus is driven forward under stress.

Both the front and rear sights are CNC machined from steel for long-term durability and finished in black to match the factory Glock slide profile.

Whether carried for everyday defense, home protection, or as a backup-gun setup, the DXT2 Big Dot Night Sights help you find your front sight fast when seconds matter.
