I'm really a fan of Trijicon sights. They really take a beating! I've broken Glock plastic sights clean off my guns racking them against barricades and such during 1 hand re-loads-
Notice the difference in my carry gun with the standard sights and my backup carry gun with the set back sights. That 1/4 of an inch set back makes a world of difference in sight radius. On my Glock 34 it's like using the irons on a SBR! ;)
