worth noting, if my memory works, that the cz52 firing pin does NOT like being dry fired, and can break much more easily than is considered normal for a military weapon. (I do own one, quite a kick and rather loud..:)
But yeah, 7.62 Tokarev is still in easy supply from what I can tell. I assume there aren’t many PPSh’s around...
I got some spare pins for just that reason.
If kel-tec made a 7.62X25 version of their 9mm folding carbine, it would sell like crazy.
