The CZ50 is a nice little gun, and the CZ70 is better.
I had a CZ-50 a few years ago, and it was both reliable and accurate, but more a novelty item than anything. And, as I shot rounds, the slide started to developed a hump on it's underside, caused by galling, as the rear of the slide pushed down the hammer with each shot. That galling/hump can become so bad that the gun will eventually fail to function. The CZ-70, with better metal processing or hardening, seemed to fix that problem.
That said, .32 acp ammo is relatively expensive and sometimes hard to find. For just a few bucks more you could pick up a better .32 or .380, or get a gun more suitable for range trips or home defense. (I got an email about an hour ago from Target Sports get a Glock 22 police trade in for $385.)
I've been there and done that, and I won't do it again. A Kel-Tec P32, which seems to be one of the rock-solid Kel-Tecs would be a far better acquisition.
