Trijicon night sights xd/xdm 45 - Trijicon Bright & Tough SP01 3 Dot Night Sights for Springfield XD Pistols

I was upset at first, they didn't seem bright straight out of the package and I thiught about sending them back. After sitting around on the dresser for a day, they got really bright and now I have to keep them under a pillow at night to sleep because they are so bright. Very bright in the dark, gives a definite sight alignment in low light situations. You will still need to see the target to hit it. Get a light too.
