CZ83 problems; maybe need gunsmith suggestions

[ScottinTexas]

So I took my almost new but used CZ83 to the rang for the first time and had the following happen:

1. First mag, perfect.

2. Second mag: couple of rounds normal, than a string of 4-5 rounds that went brrrrppp full auto.

3. Went with mags loaded with 2-3 rounds and experienced several doubles and several cases of singles but the hammer followed the slide home and put it in double action mode instead a cocked hammer / single action.

Seems like a sear / hammer / disconnect or related spring issue but I'm just guessing. FYI, was using PPU and S&B ammo. Didn't make any difference in terms of malfunctions.

Anyone else have any experience with this disease and what the cure is?

Secondly, is there a short list of qualified gunsmiths for these older models?

Here’s an old thread on this issue. I saved it because of the last comment.

I noticed there was a gunsmith with a membership here but I can't contact him; either I don't have access or he's no longer a member. It's an old thread.

I did stumble on this great reference though:

its a sear spring issue most likley. look though AC_CZ's link and also check out links within the post. its a bitch to get the sear spring in correctly sometimes but it can be done.
