and I’m sure CZ would have made it right had I done so,
My experience, unfortunately...has been the opposite with CZ. Sent my 75BD back, not fixed "no issues found". I eventually solved the problem.
Sent my 527 mags back, sent me new ones with the same problem. CZ refused to accept the fix I discovered.
All they've really done is just install new parts and hope it works.
And yes, the CZ handgun triggers are atrocious, at least the DA/SA versions.
One last thing, hose out the guts every now and then with Powder Blast. You won't believe what runs out the bottom. The clockwork is fairly complex and grit can really wreak havoc with it. Take the grips off first though.
