Or, judiciously use a dremel to take the sharp edges off. That was the case with my second CZ -- an 85 Combat. (Have had a BUNCH of CZs, over the years, but that 85 Combat (satin nickel) is the only one still in my gun safe -- along with a great Kadet Kit.)
Other triggers ARE available, but don't order the flatter, straighter SINGLE ACTION trigger if you want the gun to work in DA mode, too. (You might be able to make it work DA/SA, but it will probably take some adjustment.)
Check out Cajun Gun Works for a lot of trigger options; and CZ's Custom Shop now offers a new short-reset trigger that might be worth the price. (It'll be smoother, and also reset better, with less take up.)
