Since others might get in the same jam I am, here is what I learned from interested anonymous persons on this site:
1) increase sear engagement.
2) Make sure extractor works properly, that it moves away from the rim as bullet is chambered. If it does not move, it becomes a firing pin.
3) clean up curled up metal (peened) around rim recess on bolt face. Use small file. (this one I don't feel so courageous to try yet). Take a look at the cases that went off by themselves and look for a firing pin mark. If none exist, you probably have insufficient headspace
4)Add shim/spacer between barrel weight and slide.Can use an O-Ring, a soft plastic strip you make yourself that look like bread clips,or metal duct tape in layers to see if it will work. See an example here on page 4 of this slide show

5) European ammo has a shorter back and is more desirable for this gun.
6) Magazine springs pressure issues that might cause deformity on bullets head.
"a spring for a High Standard magazine has exactly the same dimensions (OD and ID) and exactly the same pitch (coils/inch). The wire diameter is significantly heavier. THe High stand spring is a lot longer. I cut the High standard spring to the same length (same number of coils) as the original IZH spring and re-assembled the mag. With High Standard spring in the mag the spring pressure measured at 3.5 - 4 pounds. PROBLEM SOLVED!!!!! No more misfires. I replaced the springs in his other three mags and he hasn't had a misfire in over 1,000 rounds. You can get High Standard magazine springs from Wollf Co.

7) Here is the answer from the US distributor EAA regarding spare parts and magazines: "We stopped import on the IZH35 a few years ago and have no mags remaining , we are very limited on the parts that we have remaining for the gun as well , the best thing to do is give us a call @ 1-800-536-4442 M-F 7am-4pm eastern time and provide a listing of the parts that you are looking for and we can talk with the techs to see if the parts are available."
