The Benelli M1 Super 90 is an Italian made semi-automatic shotgun with an inertia-driven recoil system that was designed by Bruco Civolani. It was initially marketed by Benelli Armi S.p.A toward military and law enforcement and was succeeded by the M2, M3 and M4 series.
The M1 Super 90 was popular with European law enforcement officers, specifically used during riots and protests due to its durable construction, easy maintenance and reasonable price. Several models of the gun were released, including the Slug gun, Entry gun and Defense models.
The Italian arms manufacturer has worked its way into the US market with the help of German company Heckler & Koch, and the Benelli M4 Super 90 has become a combat weapon with the US military.
