XS Sights delivers the DXT2 Big Dot night sight set, engineered to keep your sight picture intact when focus shifts downrange during defensive situations. The yellow dot features high-contrast coloring optimized for visibility across bright and low-light conditions, while the convex design absorbs ambient light and glows when illumination drops. Steel construction with tritium front and rear elements ensures reliable performance in any lighting scenario.
This set fits Glock 42, 43, 43X, and 48 models and maintains compatibility with standard holsters. The DXT2 Big Dot Defensive Express configuration pairs a tritium-filled rear sight with a tritium front sight and yellow dot, delivering the rapid target acquisition characteristics that define the Big Dot platform.
