Had a pair of Warren Tacticals fixed night sights put on my Glock 22. They were bought as a paired set from Brownells. Took the gun out for the first time with factory PMC 180 grain FMJ,s and it was shooting about 3 inches high at around 50 ft. The Tech at Brownells had me measure both sights for height and he thought they were the correct height off of the slide to top of each sight. I told the tech I was shooting a KKM Barrel so he told me to put the stock barrel in and shoot some rounds at the same distance. Did that with the same results still shooting about 2.5 to 3 inches high. Any suggestions. I know I can get a taller front sight but these sights are suppose to be a match pair.
