Here are pics from an online seller:
The top gun is the CZ-50; the bottom gun is the CZ-70, a 'slightly modified' successor. They are in 32ACP, and were Czech police issue. My guess is that the significant change in the -70 is the shape of the backstrap, and that it was done to reduce the incidence of slices in the web of the thumb.
