I have one of the CZ70's. Basically the same gun, with a few minor changes.
I prefer the shape of the 50's grips, and replaced mine with a set.
The DA trigger on mine, and a couple of others Ive shot are terrible, and are easier shot using two fingers. SA is pretty good. Its one of the few guns I thumb cock.
They are well made, accurate little guns. A little heavy for their size. .32's arent the cheapest for plinking, unless you reload.
The only real problem I had with mine, was getting the mags straitened out. The mag that came with the gun, as well as some I got from Marstar that were supposed to be new, but werent, would not function with more than three rounds in them. Turns out, the srings in all of them were bad, and when replaced with some from Wolff, work fine now.
