Beware! not for the novice or faint of heart - ZEV Technologies PRO Flat Face 9mm Glock Trigger Drop-In Kit

This trigger is a mess. Out of the box it was incorrectly assembled and flat out dangerous. I installed this trigger into a PF940v2 frame straight out of the box with no modifications. A function check revealed that the gun would have fired when pressure was released after trigger reset. The only way to make it function correctly was hold the trigger, draw the slide back,release the trigger and drop the slide. Pinning the trigger through the cycle caused it to function like a binary trigger lol. Upon inspection I found that the trigger spring was installed backwards, which cause some issues with cycling. I replaced the connector with a stock one I had laying around and reinstalled the trigger spring correctly. This fixed the double fire issue but revealed another.The trigger safety lever was too long and didn't clear the frame ledge during normal cycling. I had to put a finger behind the trigger shoe to push the slack out to get the trigger safety to engage. A little work with a file on the back of the trigger safety fixed this issue and now everything works quite well. I have a few hundred rounds though it with no real issues but had to complete reengineer the trigger to make it anything less than crazy dangerous. I would call this a "diy trigger kit" rather than a "complete trigger" and for that it's over priced... Even on sale.
