Another wonderful set of sights are the trijicon HD night sights. The rear has a large U notch with tritium inserts, and the front post has a tritium insert with a HUGE photoluminescent painted ring. Not exactly the most precise sight out there, but definatly an awesome battle/defense sight because of the quick aquisition of the front sight. I know, I sound like a salesman, but I just got a set and im just itching to go shoot. haha
