Good upgrade - ZEV Technologies Fulcrum Ultimate Trigger Kit, Trigger Pad w/Safety, Gen4 Glock 17/19/26/34 w/Dragonfly, Gen4 Pistol Slide,G17 Absolute Cowitness w/RMR Cover Plate

Good upgrade, but a little on the pricey side. The trigger face is a huge improvement over the stock trigger and the striker/spring kit does reduce the perceived pull weight and trigger travel. My only real complaint is the supplied trigger connector. I tried it out and ended up uninstalling it because it seemed to make the trigger a little mushy. By that I mean it became more difficult to feel when exactly the trigger would break. I personally preferred it without the connector, but to each their own. Overall, good buy.
