Me too! I got mine installed last week, while I was on an expeditionary outing. I ended up getting the Trijicon GL 24's for my G21. I was going to go for the Ameriglos, but changed my mind. I knew I needed to upgrade my sights, when I tried finding my front sight in the dark, between the garage and the house, and I couldn't see the front at all. I could make out the U frame on the rear sights tho, but, why just change out the fronts? Especially since Glock factory sights are plastic.
