It really depends what kind of Tokarev you are talking about.
There are 3 major kinds of TT33 that are available.
1. Chinese TT. These guns are frequently junk. Poor machining, nadly put together. some exeptions do exist, however.
2. Polish TT. Much better made. Good quality steel (actualy Chinese also use good steel, they just mil it badly). These guns are good shooters, and thet are cheap.
3. Soviet TT. These are rare. They are very well made, but most of them have been issued and re-arsenaled at some point. Most of them have manual safety installed for importation reaons.
Having said that. If you ever see original Soviet TT33 with no import marks and no manual safety, buy it. They are collector's items. these guns would be pretty havily used, but very nicey made. Quality would be about as good as US M1911A1 of pre-WWII manufacture.
CZ-52 is a good gun, but despite the fact that it is rummored "the strongest pistol built", this gun has never seen real action.
In years that it was used by Chechoslovacian army it was re-arsenaled at least two times, and every time some changes were made to the design of the gun. It does use roller lock, which is normally found in Hk rifles as well as P9 pistol. While interesting in design, this mechanism is quite complex and is not the strongest, or the most reliable. all it takes is for the roller bearing to jam, and it will take a mallot to open the slide. also the firing pins in CZ-52 are made from very hard steel. So hard ir will brake it you dry fire the gun (am not talking about allot of dry firing).
CZ-52 also has a de-cocker, which is somewhat dubius, since it iws a single action gun. Because of firing pin safety you can carry this pistol with round in the chamber and hammer down. The question is why. As far as hot ammo, Soviet TT-33 will withstand it just as well as CZ. After all, TT and PPsh-41 were using the same ammo.
I would nor reecommend ither of these guns for defense carry.
