ZEV Technologies

The ZEV professional starter spring kit provides a lighter and smoother trigger pull with a positive reset for your Glock by combining our popular competition spring kit with the all-new ZEV pro connector. The ZEV competition spring kit contains a heavy trigger spring (heavier is better as it assists with trigger pull) a reduced power firing pin spring and a reduced power firing pin safety spring. The ZEV pro connector was engineered to provide users with a consistent positive reset and a reduction in trigger pull weight without sacrificing the reliability or safety of your pistol.
