You don't need a trigger kit to fix the creep. Just follow the manual's directions for adjusting the trigger. CZ triggers are excellent and do not need to be replaced with a kit. However, they are typically maladjusted from the factory. Use gun scrubber to degrease the threads of the adjustment screws, then use blue loc-tite to set them. You will only need to adjust one of the screws and it is not rocket science to do it. Just a couple of screwdrivers are necessary.
