The ZEV Technologies Competition Spring Kit contains an extra heavy trigger spring (heavier is better, as it helps you pull the trigger), a reduced power firing pin spring, and a reduced power firing pin safety spring. The result is the lightest and smoothest possible trigger pull for your Glock. Fits all models (Does not fit the G42/43)

    Spring kit arrived in a very timely manner and was just as described. Made a noticeable difference in the trigger lb pull. Also, was a lot cheaper than replacing the whole trigger assembly. Easy to install.

    Purchased this kit to help with trigger pull and it helped more than I anticipated and is reliable after 200 rounds. I highly recommend this kit!
