Since I was having extraction problems I replaced the extractor and spring in my CZ 83 7.65mm and it solved the problem. Actually just cleaning the extractor channel took care of the problem but I replaced the extractor anyway. I was looking at a number of the spare parts that are on Apex Gun Parts and the write up description for many the items say that the parts are only for the CZ 83 in 380 or 9 mm Makarov. Is there anyone else selling used parts for the CZ 83 I wanted to pick up a few springs while they still available. I tried CZ USA website but a couple of the springs were not available. In addition, CZ USA parts webpage has 5 different trigger bar disc connectors with different numbers but no description. Does anyone know which one is for this is easy 83 in 7.65 mm? Thank you.
