Since you got it NIB, if it's one of the ones from Europe the box should be a styrofoam container with a thin open-ended cardboard cover. Inside there should be cutout for the pistol, the extra mag, a cleaning rod, and there should be a test target and a manual in Czech, English, German and French. I've heard the imports have a different grip, your grip should have the CZ logo near the bottom. I've also heard all the imports had a half-cock safety, but I don't know what year that started. If the original owner got yours in Europe there's no half-cock safety, the only "safe" options are hammer down on empty chamber or cocked/locked. Also, I've heard about differences in the magazine well, yours should freely drop an empty mag. This is probably the same as imports, but the s/n should be on the right side on the frame, the slide, and the barrel. If you have questions about something specific let me know and I'll check.
