I've been reading a lot of threads on this site and others regarding the stock sights on Glocks. I've heard a lot of people complain about how bad they are. Just wondering why everyone thinks they are so bad. I'm very new to this and have only been out shooting with my gun (Glock 19) a few times so I don't know how to tell if the sights are bad or not. I'm just learning so I don't know what's good or bad yet. I'm taking a basic pistol class/CCW in a few weeks so maybe I'll get more insight there but just wanted to hear the opinions on this board. Thanks!
