Have an acquaintance that waterfowl guided and also shot competitively some years back. He berated the Benelli autos because, IIRC, they had a roll pin or some such in the action that had a rather short life span and was prone to fail abruptly. This outcome was accelerated by 3 1/2" loads. The Beretta autos were his choice for function and perpetual longevity in less than favorable environments. YMMV....
