They are made by the same company that makes barrels and parts for the Beretta/Benelli/Franchi brands. The company is Stoeger SSA and is located in Istanbul, Turkey. Many of the parts for the high end guns are made with Stoeger's computerized CNC precision machining and shipped to Italy for assembly in the big dollar guns.
Stoeger SSA does not make parts for the ER Armentino guns made in Brazil and marketed as the Condor and Uplander. These South American guns are made under contract with Armentino, who makes guns under the brand name of Boito.
I have a couple of the Turkish semi-autos and one Uplander made in Brazil. Thus far, they have been satisfactory.
