Benelli semi-auto 3rd generation (inertia recoil) shotguns were imported starting in the late 1960s..... The SL80s are much lower priced than current production Benellis. Since the late 1980s, the Benelli SL-80 series marketplace has dropped sharply, and relatively few guns have been traded during the new millennium. In the past five years, there have been an increasing number of SL-80 guns for sale which have had unresolved mechanical problems. Parts are scarce and high priced. Wood for most models are no longer available. Buyers would be well-advised to be cautious when considering buying a used SL-80 series Benelli.
