I've tried them all and these are my favorites - Ameriglo Glock Tritium I-Dot Night Sight Front and Rear Set

These are like having the front of a Trijicon HD, rear of Heinie Straight 8's. The rear is press fit so you use a sight pusher tool to install, so they will stay once you get them in place - no set screws that will eventually come loose or that are weaker when hit with something.
Rear site has shelf for racking one handed. Maximum value with a decent price and highest quality available.
