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.
If it jams force it! If it breaks it needed replacing anyway.
