ZEV Tech Adjustable Fulcrum Trigger Drop-In Kit - Black/Red - Gen 1-3 - 45ACP
The ZEV Tech Adjustable Fulcrum Trigger Drop-In Kit comes with all the components to replace the entire factory firing assembly making this the single best upgrade you could do to your Glock. The trigger features an integrated safety that allows full trigger performance with no compromise in safety, while trigger pre-travel and over-travel are screw adjustable for further user customization.
*Note: The differences between ZEV's Drop-In Kit and the Ultimate Kit are a Skeletonized Firing Pin. The benefit of adding the Skeletonized Firing Pin is its lighter construction, polish, and the tip of the firing pin is extended for more positive primer ignition.
*Glock Model Application: Gen 3 or earlier - Glock 21, Glock 21C, Glock 30
