The CZ-52 was an imported semi-automatic pistol. Here is a brief overview https://en.wikipedia.org/wiki/CZ_52 and here http://makarov.com/cz52/index.html
Back in the 90’s this, and many “commie” guns, were a readily available on the free market. I bought one after a friend showed me his, it seemed like a fun gun for under $125. The original CZ-52 came in 7.62×25. I love this round.
