I have been shooting a Glock 19 since December 2011, when I returned to shooting after 25 years. My eyes are not what they used to be and the factory sights don't work for me today. I have read numerous posts on night sights and the pros/cons of various vendors. In fact a buddy of mine gave me a set of Trijicon sights to try out. They were too small and not very useful for daytime target shooting. Because I primarily use this gun for target practice, what I think I need are higher visibility standard sights for the Glock. I have read where the XS Big Dots are great for target acquisition, day or night, but not great for my intended use: target practice at 15-25 yards. I spoke to the XS factory folks and they recommended a standard XS express tritium front sight and a non-tritium rear site to get the advantage of their "lollipop" sight picture. Does anyone have this set-up and can provide feedback on it or perhaps an even better alternative to my needs. Any help or suggestion would be welcome. Thanks in advance.
