I have a Stoeger Condor II over-under in 20 ga. It was the last of an old run with no ribs between the barrels. It was a demo item that I later determined had been back to MD for repairs once before I bought it. Two trips to MD later I had gotten discouraged because it still misfired often, so I set it aside for several years.
I mentioned the gun to a new-found gunsmith who asked to give it a try. He simply fitted the new parts that the factory gunsmith @ MD had just dropped in, adjusted springs and the firing pin protrusion... problems solved.
My belief is that it is a good utility grade gun but that factory support is a joke. Maybe being made in Brazil is an important factor, but I don't think so. Then again, I probably wouldn't buy another one.
Oh yeah, I bought it to shoot a bunch of local informal skeet events to "save wear and tear" on my Model 90 OU 20 ga. Bad choice, but the M-90 still looks pretty good.
