Hi. I have a 2002 CZ83 that had been driving me nuts with a failure to feed problem. I posted here, months ago and got some recommendations for a fix. Nothing worked. All 3 of my 10 round mags would have a FTFeed on the 2nd to last (2nd round loaded into mag) round, necessitating mag removal then shaking out the round.
UNTIL a few days ago!!
I e-mailed gunsmith@cz-usa.com and Mike replied. He said the feedlips on the mags might be spread too much.
So I got my hammer, some duct tape to protect the finish on the mags, and gently hammered each mag till the feedlips measured ~8.5mm at the open end.
I fired off 40 rounds from each mag (120rnds total) without a single jam. This HAS NEVER HAPPENED before!!!
Previously, I couldn't shoot 3 mags without 2 FTFs as described. The feedlip dimension was/is really critical, and an easy fix!!
Hope this helps with some of the feed problems I've seen posted here.
Of course CZ's Mike, offered to replace the mags if I returned them, but hey, now they work fine!!
