So just for information, the Eemann Tech Ultimate Springs Kit for CZ doesn't tell you what the trigger pull weights of the trigger will turn out after the installation.
I don't have a trigger gauge either, but hacking together a coat hanger, and several liter containers I've approximated the trigger weights that one may expect and how much the trigger pull weight went down.
Factory OG CZ 85
Stock: DA 11 lbs ish, SA 6 lbs ish
Ultimate trigger kit: DA 6.5 lbs ish SA 3 lbs ish.
All values are subject to variation as a coat hanger isn't a precise trigger puller, but you can rest assured that installing a Ultimate spring kit won't kick you out of IPSC Production where DA/SA requires a first trigger pull of 5 lbs.
It is remarkedly lighter than factory and it's a quite inexpensive upgrade ($40) for that kit + the upgraded trigger pin ($15) to make shooting the CZ 75 remarkedly easier.
