Informational tidbit: while an almost exact Tokarev clone, the correct designation for the Polish version is "Radom Wz48".
Aside from genuine Soviet Tula Tokarevs, Polish examples are a close second in desirability for collectors.... and by some estimations, higher quality. Indeed, my own 1952 Wz48 is very well made.
While the differences in fit-&-finish between Russian, Polish, Chinese, Romanian, & Yugoslavian Tokarevs aren't easily visible, the quickest way to assess the quality of a Tokarev is to grasp the slide and try wiggling it side-to-side. Any large amount of lateral play between the slide & frame will effect accuracy, and from what I've seen Russian, Polish, & Chinese TTs have the tightest tolerances.
