The zev ultimate fulcrum trigger. - 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

The zev ultimate fulcrum trigger is great trigger for the glock. I was truly surprised how clean and crisp the break was and how short the reset is on the trigger. The down side is the price, so if you can get over that you will not be disappointed. I've put about five hundred rounds through my glock 17 with the zev ultimate fulcrum trigger without a single problem. The installation of the product was easy; there are plenty of reviews and installation videos on you tube.
