If I am unable to repair them, I get rid of them. Now having said that, the only magazine I've ever had problems with was a CZ- 70, da** floor plate came loose and dumped every thing. The rest of my magazines I've had very good luck with, I can't remember when I had a bad magazine that I couldn't fix ( other than that CZ-70 }. BTW, on the CZ-70 , one of my friends mentioned he had a CZ-50 mag that he needed the internals, problem solved, two became one.
