Trijicon Night Sight Set Green/Green XD/XDM/XDS
Nighttime and low light shooting tests prove sights
equipped with these glowing dots are easier to see and
more accurate than instinctive shooting with standard
black sights. Rugged, heavy duty, Traser, luminous, 3-Dot
tritium lamps provide their own long-lasting energy source.
Lamps are mounted in silicone-sealed, metal cylinders to
give maximum protection from breakage or leakage. Polished
sapphire, crystal windows give a bright, crisp and perfectly
round aiming dot in low light. Inlaid white rings around
each sapphire make the sights appear as standard white
dots in daylight. Very narrow blades do not have the
white ring and will look more like a plain black blade in
daylight. Fits All XD, XDM, and XDS Models.
