XS DXW2 Tritium Night Sights offer the best front sight visibility in all lighting conditions. DXW2 sights drive focus to the front sight using a high-contrast front and a V-notch rear for an unobstructed view of the front sight. DXW2 front sights use a patent pending glow dot that absorbs light and glows in low light levels before it is dark enough to see the tritium. The increased surface area of the convex dot increases light absorption, intensifying the charge of the glow properties of the dot. The dot-the "i" sight picture, with a tritium dot in the front sight and a non-tritium white stripe in the rear, prevents confusing the front and rear sight in high-stress situations. In most gunfights, the victim and attacker are both moving and the victim's focus is drawn to the threat. The wide field of view increases visibility of the front sight and of the threat downrange.
