I have these installed on my G26 and for the most part really like them. However, I also own the S&W 327 Nightguard with XS 24/7® standard dot tritium front night sights and Cylinder & Slide Extreme Duty fixed u-notch rear sights. I really like these rear sights as they frame the dot perfectly. Much easier than "dotting the I" on my Glock sights. The Cylinder and Slide web site does not list the rear sight as being available for anything other than S&W revolvers. Does anyone know of a rear sight that would work the same with my Big Dots front sight on my Glock 26?
