XS Sights’ DXT Big Dot Night Sights for Glock are an excellent choice for those who want to enhance their EDC pistol’s performance. Designed for defensive use the DXT Night Sights feature a reflective white dot that bounces ambient light to provide increased low light visibility alongside the glowing tritium center. The front sight is large and highly visible which helps solve many issues from aging eyes to deteriorating vision. The high-contrast white front sight is complemented by the low-profile V rear which provides greater visibility of the front sight. The simple dot-the-“i” sight picture prevents confusion between the front and rear sight in high-stress situations. The rear sight has a white outline with a tritium center and the rear sight ledge is designed for one-handed slide manipulations. Front Sight Dot Width: 0.188″ Overall Sight Height: 0.405″.
