The differences between the 82 and 83 are as I said, slight involving the types of pins used. The markings are very much like those on the CZ-52. That it say, other than Century's import marking, there is no original model designation stamped on it. All you get are some proofs, a manufacture's code, a date, and serial numbers. Interestingly, the frame serial number is stamped on the barrel housing, which of course, is integral to the frame. The result, though, is to leave the impression that the barrel and the slide are the only serialized parts on the pistol. As it turns out, the barrel is not numbered, only the frame and the slide. Other than that, the pistol is identical to early CZ-83's, using what the Czechs called a "black varnish" finish on the frame and slide. All other parts such as the safety, slide release, trigger guard, and the like are blued. The CZ-83 has roll pins instead of solid pins, generally comes in a less utilitarian finish, and has commerical markings like the CZ-75 or CZ-50. It is interesting to note that the 82's and 83's were produced at the same time and likely the early 83's had the same type of pins that the 82's had. Indeed, the early 83's were really just 82's made for the commercial market. That compares the .380 83 and the 9mm Mak 82. I cannot comment on the .32ACP version of the CZ-83.
