XS Sights GL-0009P-3Y DXW2 Big Dot Fits Glock 17/19 YLW

XS Sights GL0009P3Y: DXW2 Big Dot 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 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 victims focus is drawn to the threat. The wide field of view increases visibility of the front sight and of the threat downrange.
