I just want to add - I haven't done anything to improve accuracy on the CZ. The trigger is adjustable (I left mine at the factory setting). There are trigger kits for the CZ (Brooks, Timney) which will give a lower trigger pull. I guess a lot of people also bed the actions on their CZs which can improve accuracy. All I ever did was check that the barrel was free floated (it was).
Something I did not like with the CZ is that I had to buy a 20 cal cleaning rod because the bore is tight and some part of the magazine well makes contact with a 22 cal cleaning rod. On the plus side the tighter bore enhances accuracy.
