I think this is a problem with the Czech naming system. From the info I'm seeing, it was officially the Česká zbrojovka Vz. 82 (9x18mm Mak), but the civilian export version is the CZ83 in .32, .380, and 9x18mm Mak.
The 82 refers to the year it went into service. There are a few brand new ones around, but rare.
