This question comes up often. I'll give my usual reply for what its worth. Stoeger is a Turkish company. They have been around a while. They have a beautiful, state of the art factory in Turkey.
When Benelli came out with their inertia driven action for their shotguns Stoeger copied the mechanism exactly. Benelli immediately sued them and won in court. The ruling said that Stoeger could only sell the gun in Turkey. This would have effectively ended production. However a team of lawyers and Benelli representatives visited Stoeger, were so impressed they bought the company. Stoeger serves as Benelli's entry level gun. It doesn't have the cryogenic barrels, the energy absorbing system in the stock, or the overall Benelli finish. However, it is a good gun and works well. The inertia mechanism is simple, easy to clean (all the gas goes down the barrel), and works well in rain, mud, etc. You can't beat it for the price. It does have a kick though so I wouldn't use it for all day Dove hunting in Argentina.
