It features the proprietary Benelli inertia system of operation.
[3] The inertia recoil system was developed for the Benelli M1, M2, and M3 shotguns in the early 1980s.
As a result of inertia, heavier loads cycle in a shorter amount of time.
[4] The M2 Super 90 is marketed as a tactical or defensive shotgun to military and police forces as well as to civilian hunters and target shooters for skeet, sporting clays and trap shooting.
[5] Exhibition sharpshooter Tom Knapp used a Benelli M2 in many of his shooting demonstrations, breaking 10 clays in 2.2 seconds with the M2 and an extended magazine.
