Ok I have a Glock 26 with Glock night sites on it. I shoot it fair. I have a 19 that has XS sights on it that I shoot pretty good. I figure when I add a 19 mag with the sleeve the only difference between the two is sights and a little sight picture. I am wondering if maybe changing to the XS sights would help me shoot the 26 a little better. I prefer the 26 to the 19 for AIWB.
