Based off the Russian TT-33 Tokarev designed by Fedor Tokarev and influenced by John Brownings 1911.
Used in Yugoslavia as a service issued pistol. It uses the 7.62x25 cartridge, based on the German 7.62x25 Mauser cartridge. A necked pistol round.
The key difference from Russian versions is the 9 round magazine, the Yugo was built to accept rather than standard soviet 8 capacity.
Supposedly the safety was installed entourage to America by a third party rather than the Zastava plant.
My pistol is very surplus-y and needed adjusting on the sights and the safety switch.
