Zastava is very well known manufacturer of firearms in Europe, just not well known in North America.
There is absolutely no comparison between this pistol and Norinco. NONE.
Arguably, Zastava makes better AK 47 than Russians, and best SKS in business.
Their pistols are very, very good as well.
When you mention that this particular model is copy of CZ99, we should elaborate on that a little.
CZ99 is pistol made by Crvena Zastava, in Kragujevac, former Yugoslavia, and now Serbia.
This factory has nothing to do with well known CZ- products that are coming from Czech Republic, that brought us famous CZ75, Shadow, Tactical Sport and numerous other handguns, rifles, shotguns etc...
Czech CZ stands for Ceska Zbrojovka, and every similarity in name between Serbian CZ and Czech CZ is purely coincidental.
Now back to this pistol that OP mentions.
It is an excellent firearm, in my opinion technically based on SIG 226, finish marginally less pleasing, while mechanics of it are possibly tougher than original.
It is mil spec, used by Serbian military officers, police and special forces.
Ergonomics, reliability and design are very good.
For individuals that like SIG 226, this is an excellent and cost efficient alternative.
