The only symptom I detect is that 2 trigger springs broke. I'd LOVE to know how a 'botched action job' did that - really - not a rhetorical thing.
Nowhere does the OP say a trigger spring broke. That was the educated guess of other people in the thread. He's certainly heard from the gunsmith what the problem was and just hasn't said. We don't know for sure.
I can't imagine a botched trigger job would expose a TRS to breakage after 30 rounds, but again, we don't know if any TRS was broken. However, a botched trigger job might screw with the timing such that pieces get tied up and the trigger can't reset. I would have advised him, as someone else did early on, to get the pistol back from the smith and diagnose/fix the problem himself, with our help. It's quite possible the smith simply took it apart, put it back together, and said "Hmm... works fine." Given the number of times I've heard of people who have taken CZs to smiths who had no idea how to work on them, I would never take one to a smith that didn't specifically specialize in them.
