I've got a CZ-50, which is basically the same gun, just older.
A friend bought a Walther PPK in .32 at about the same time, and my CZ-50 is much more accurate, about the same size, and about a quarter of the cost...
The only problem with these guns is parts, but little things like firing pins can generally be found (however, they are pricey.)
Magazines are the biggest bugaboo -- as most people with either of these guns experience big problems with the mags. They can be tweaked. Buy a couple of new mags from CDNN ($20?)
