I know nothing about the CZ but had a Star Model 30MI for a long time and it is one fantastic gun. Accurate, built like a tank, and takes down in seconds. The recoil spring is in a keeper so you don't need to compress it when re-assembling and, as someone's already mentioned, you can completely tear it down without tools. Before anyone says that mags aren't available, know that Ramline's 17 round S&W 5900 series mags work in it. It's haevy so it's no carry gun but that weight makes for very little felt recoil. It'd be a great range/house/car/shop gun.
