The Tokarev is not as strong as the '52. (Especially the early Chinese imports) Be aware that much of the SURPLUS 7.62X25mm ammo is intended for SMG's, and will have insensitive primers, and heavy loadings. While fun, making a steady diet of em in a CZ 52 is unplesant. I suspect these would eventually destroy a Tokarev.
Sellier& Bellot makes a very fine, reloadable 7.62X25MM loading that works in the CZ 52. (and is NOT heavily loaded.)
The Star B is a decent pistol, and the couple I've seen were in very good condition.. My only concern was magazine, and parts availability..
The Ballester-Molina is not a terrible pistol, but it's not a great one either. The steel the Argentinians used tends to be softer than one would expect on a 1911 type pistol.. This does not mean they're unsafe, just that they'll probably wear faster.. Great gun if you want to try diffrent sights prior to mounting em on your expensive 1911. Parts interchangeability with a 1911 is not terrible, if you're mechanically inclined, and have a source ofCHEAP 1911 parts.
If you're looking for a 1911, get a Systema, or a U.S. 1911..
