Was shooting the CZ 82 recently, and it’s still shooting a bit low for. I just installed a #5 (the highest) rear sight, so that should do it for me. Haven’t had it to the range yet.
You are the only guy I have heard report the CZ 82 shooting low.
I hope the sight corrects the issue.
Mine shot low (cz82) Instead of filing I painted the front sight only half way. Now its almost a nail driver.
Try left handed. Might be ‘my-right-hand-shoots-lower-than my-left-hand’ syndrome.
