Commercial finishes as sold in the Rod and Gun clubs in USAREUR in the day were black enamel, blue, and parkerized. Nothing special in any case but the enamel was the worst. The parkerization under the enamel was a crude undercoat not the same as the final park job on the others.
KEEP in mind that the CZ 75 was a commercial product. The Czech military didn?t use them and no east block countries did either.
Look inside a PreB and see why the trigger OTB is pretty mediocre. The double hook hammer interface makes it a bit complex, and as one can tell these things had crude machining. So, it is normal to have grit and the camming is what I call 'variable'. Sometimes it breaks early sometimes late. Some CZ 75s can exhibit three different breaks in SA. DA after polishing or 1500 rounds gets pretty good. With good polishing the DA can beat a Smith and Wesson revolver.
Always remember the whole Warsaw Pact was third world. It was orderly and somewhat clean depending on country, but third world nonetheless. So manufacturing was crude.
But the cool factor on the PreB is great. They are combat accurate (sometimes more so) and reliable, slim, and they just look so nice with their NON-Beretta round TGs and indented straight serrations, and beautiful lightening cuts. No goofy hole in the slide. And, they WERE made behind the iron curtain to Western likes. Hicap and cool - and of course one of the best feeling pistols ever.
If you want the best OTB trigger, get a SIG. Want a fat but good looking pistol your service chose, get a Beretta. But If you want slim/cool/beautiful/feels good, get a CZ75 preB.
