XS Sights SI-0013S-3Y DXW2 Big Dot Yellow - Sig P320, P226, P229; Springfield XD(M)(S)(E), HellCat; FN 509

XS DXW2 Big Dot Tritium Night Sights offer the best front sight visibility in all lighting conditions. DXW2 Big Dot 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. The 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.
