For sale: Used (1-2 years old) Meprolight adjustable Glock 17 / 22 night sights. These are green tritium. They are still bright and have years of life left. I didn't like the high profile of these and went back to fixed Meprolights. The rear sight has slight boogering on the left side where I drifted it into place in the slide dovetail. The right side has very minor surface boogering from my centering it on the slide. I did slightly file the bottom and sides of the base of the rear sight (the surface areas that contact the slide dovetail) to enable me to get it on my slide...but believe me when I say this sight still fit VERY tightly on my Glock 22 slide. SOLD.
