XS Sight Systems DXW2 Big Dot for Glock 17-27/31 -38 Yellow Defense Exp Set

XS DXW2 BIG DOT GLOCK 17-27/31 -38 YELLOW DEFENSE EXP SET
FEATURES:
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
The wide field of view increases visibility of the front sight and of the threat downrange.
