Hey guys, wanted to see if you I could get some opinions on the Trjicon sights. I have Trijicon Bright and Toughs on all of my Glocks so far, G19, G17, G43, and I just recently discovered the HD's. With the cost of the HD's I really dont wanna get a pair of them and try them out, I'd prefer to get opinions on them first. Are they a big upgrade over the regular Trijicon Night Sights? I have all of my Glocks set up for defense and not so much target or competitive shooting.
