Bought a CZ 83 from Mr.Don at Topper world in Gretna (DBMJR1) but the sear spring r something in the trigger is broke. Which I’ve found is a common issue with this gun. Asked for my money back but he refuses so now I’m stuck with it. I’d try to fix it but this gun is just too complicated. Anyone know a good gunsmith that is good with Cz’s? I’d appreciate any help I can get. Thank y’all
