Recently acquired a CZ-83 in .32, manufactured in the early 90's before the rollmark was changed on the slide. After the required shooting/adjusting the sights, it was time to learn how to field-strip and clean it. The tricky spring is the "slide stop retainer spring", easy to dislodge when you remove the trigger guard as it shares the same cross-pin that the retainer spring rides on. http://leolani.net/relics/cz82.html is a good tutorial/reference for this series of pistol, it took me three attempts to position the spring correctly so the trigger guard did not dislodge it again. The gun is wonderful to shoot, I did file the front sight as it was shooting 5" low to my point of aim. Nice size for conceal carry.
