wilkes, the CZ75 is very close dimensionally (not shape, but dimensionally) to a gov't 1911. So if you're a big guy like 'Tide (just sayin'), sure, you could carry it IWB with a good holster and good belt and get away with it. But being as not everyone's built that way, steel full-size 1911's aren't popular IWB carry guns.
OWB would be fine. Remember, this gun is a military/LEO sidearm by design. It has a substantial build quality, plus it's a double stack mag, so fill that sucker with 15rds or so, and it's both pistol and bludgeon.
