I very sorry you are having such a difficult time with your pistol.
For what it's worth I'm actually surprised you got in the building. They are doing their year end inventory and on the whole shebang there. They are so busy they have to goof off after they get home and on their own time. There was a rumour going around they were going to issue Adult Depends just to save time not having to go to the bathroom.
Seriously they aren't normally that brusk they really are up to their eyeballs with the inventory, and have been since Christmas. I'm really happy I don't work for CZ-USA at least last week and this week.
OK here's the deal, First off look at this site. You may well have allready seen it but pay attention to the part where he talks about disassembling the pistol and he says something about a spring being in or part of the Slide stop, and if you don't do something then you break the spring you are hosed big time. I am also going to attach a link to some pictures I took of my 82's both a ex police model that is fugly of it's best day ( they did a commercial spray paint job on them when they got them from either the Israeli or the Czech Police, the other is my refurbished 82 that I use as my back up carry pistol presuming I'm not using the 52 in the capacity.
I AM NOT a gun smith! I have very rarely about 3 times in 30 plus years, ever taken a pistol down to it's componet parts. I am a shooter, if the weapon fails and I am not in a life and death field exercise then I let the gunsmith look it over. or let someone in the squad check it if we are in the weeds. Just so you and I suppose everyone else knows I am a person that knows how to do one thing damn well. Computer hardware or network hardware or laying out a net work is what I do second to none. using the SW is NOT my deal I do not program or fix major glitches. I do not EVER work on printers they are NOPT computers, call a printer repair guy. I also am qualified to drive Executive Protection details and to defend my Principal even if they fire me for the way I do it. (They paid me to keep them alive not fore how I do it) and I know jack all about how to fix cars.) And so forth.
The stuff I just wrote is so you know that I am trying to help you to the best I can. You are a member of the forum and as such I try to see that any member gets the help they need if there is anyway I can accomplish that, and no one else can even give you a hint. Everyone here has their Strong areas, Medium areas and weak areas of experence and we are all here to learn from one another and teach what we know also. You have you realize that the 82 is not that well known as a carry weapon, and very few folks, compared to others that know about 75's etc, know all that much about them. I LOVE mine but I would never on a bet strip it down to componet parts. Frankly I admire your doing so and wanting to know everything there is about your pistol. I'm am NOT making fun of you nor belittling you, I do in fact admire you for trying.
So anyway, these are the links that I think may help you figure out what went wrong:

this is the link and or pictures of my CZ 82's, just in case you can compare them to what yours looks like. But it's more likely that the spring the guy talked about is the problem.
I truly hope this is some value to you
