AIM has the model 57.
It shows up on page 75 in John Remling's book "A Collectors Guide to Tokarev Pistols"
The difference between the model 57 and most other T-33 clones is cosmetic.
I wrote Sierra and told them their load book was wrong. The CZ52 is NOT stronger than the Tokarev. They wrote back that they just printed what they read and had no original information.
My favorite thing to do with Tokarevs is to convert them from 7.62x25mm Tokarev to 9x23mmWin. I just find an aftermarket 9x19mm barrel and ream the chamber and throat a little deeper.
The max published load for 357 mag is 8 gr Power Pistol 158 gr.
With Win 9x23mm brass [Starline 9mmSupercomp brass is not strong enough] I have been shooting 16 gr Power Pistol 158 gr. The recoil is horrific, but that is a 357 mag double load and the Tokarev can take it.
