CZ 75 series can be amazing triggers. They can also come pretty bad. Sometimes NO amount of dry/hot firing will smooth enough and they can stack pretty bad - not as bad as P series, but they do.
Had a P01 MANY years ago and it went to CZ twice, then I Opted to ditch it and moved on. Got the itch just before CCP virus totally hit the P01 prices and one was in a shop, so I bought it committed to making it 'right'. It was hard. Grit and stacking. Ended up replacing the trigger bar. Then I went the full CGW defensive route, and it is a great shooter. SA is as good as a better than good 1911. DA still stacks a bit, but it is a 'smooth' sort of stack, and the SHORT pull from the CGW hammer makes it nice. These guns are just naturally good shooters. Too bad that they cannot get the QC on the triggers right.
