Zev "duty" drop in trigger - Zev Technologies Duty Drop In Trigger Kit Black Trigger Pad With Black Safety For Gen 1/2/3 Glock 9mm DRP-9-TC.B-B

The trigger safety is held in the shoe by what appears to be a small screw with a generous amount of red Locktite. The pivot and trigger safety screws do not thread all the way through the shoe. I would not trust this system for duty or edc/ccw use. I recommend the Overwatch Precision triggers also sold on Optics Planet. They use coil pins that are much more secure, and use a factory GLOCK NP3 coated trigger bar. Take-up and over-travel are removed only to the extent that the GLOCK safeties still function.
