Zev trigger - Zev Technologies Fulcrum Ultimate Trigger Kit Black Trigger Pad With Red Safety For Gen 4 Glock 17/19/26/34 ULT-4G9-B-R

Glock upgrade newbie review: I like the adjust-ability and the feel of the flat face trigger. The included connector did not work for me, it would not fire with it. I used the stock connector, heavily polished with 1500 sand paper and Flitz. It seems very expensive to me for what you get. They should offer more color combination like Pyramid triggers.
