I installed the combat trigger with overtravel stop, and used a reduced main spring, and I have a wonderfully smooth and usable double action trigger now. I find that the Canick single action reset is fine. These are very very good guns. Polishing does wonders.
BTW - I kind of like the C100 trigger in certain aspects. The SA on these is decent and has a short camming - much shorter than the CZ. The half cock seems to be a bit more cocked than the CZ - which makes for a SHORTER DA pull. Most You Tube jockies don't know how to decock these guns safely and miss out on what is a VERY good DA pull once it is polished - short an smooth - one o the best in the business. The reset is a tad shorter than a stock CZ and is very tactile. Also, the DA SEEMS to be exceptionally smooth once smoothed and broken in.
