Looking for suggestions on how to fix double fire on a IZH 35M.
If a specific ammo helps eliminating double fire, can you name it?
Thanks

Search these fora - the subject has been discussed extensively.
From the amount of wear / peening of the breech and breech block that occurs on one used exclusively with target-grade ammo, it's pretty clear that these pistols are made from inferior material. Use only standard velocity ammo to give them an easy life.

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 http://news.webshots.com/album/65975805Baeysx?start=36
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. http://www.gunsprings.com for about $5 each."
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."

Good choice! This is NOT the right way to fix this. If metal has gotten peened into the recess, you are much better off peening it back in place. This will probably require making a special punch, but somebody with a lathe could make one for you very quickly. With luck, the metal will be work hardened in the process, and will be less likely to peen back.paulo wrote:3) clean up curled up metal (peened) around rim recess on bolt face.

The more common problem is metal getting peened into the chamber by excessive dry firing. It's such a standard problem that they sell a special tool that swages the metal back in place. Much better than removing metal that ought to be someplace else.
