I just picked up a new CZ 75 and when I got it home I began messing with the trigger pull. The double action is pretty bad but the single action pull is the worst I have ever seen. I ordered this gun new and really did not think to walk through the trigger pull at the store. It's a new CZ hell it should be good. Well it's not. Called CZ this morning and explained the single action trigger pull is about 5/16" and it feels like I am crushing a bag of Lays Potato chips. (No really) They said send it back we will fix it. We will see what happens. It's going back next week.
