The CZ 52 is a really fun gun to shoot. The 7.62X25 round features a light bullet at high velocity. It makes for a great range gun, but not so good as home defense, or carry. Theat ALL surplus ammo as corrosive, regardless of the sellers claims.
For a reasonably priced milsurp, the CZ 82 is and excellent choice. In looking through all the distributer's flyers and websites, they are still being sold. The supply of 52s are pretty much exhausted, so the prices are probably higher than the were and climbing.
The CZ 82 is not only a fun gun at the range, but also good to double as a HD or even CCW firearm. The 9X18 ammo is a little more costly than the surplus 7.62X52, but is available.
Another choice in a milsurp pistol for the 7.62 round would be the Polish or Romanian versions of the Russian TT33 Tokarev. Another interesting and fun pistol.
I have all three, and enjoy shooting each of them.
