Haven't tried the Zastava, but now this thread has me interested in one. Looks like they are going for the $250-300 range.
I did have a Norinco Tokarev in 9mm I shot for several years. It never missed a beat and was a great gun. Wish I hadn't sold it. It looks identical to these Zastava with the exception of the safety. Should be a great gun if you choose to get one.
