I have a Norinco jw-21 lever action 22 with a broken firing pin striker and can't find a replacement. I have been told that the JW-21 is a direct copy of a 9422, looking at the parts diagrams online, the parts look the same but I have no way of knowing for sure. Just wondering, has anyone really compared the two? I have also thought of making the striker, looks pretty simple but not sure what kind/grade of metal to use. Ideas anyone?
