The M1014 is the Benelli M4 Tactical. It is available only in semi auto. The Benelli M3 is the closest thing you'd find - it has the "dual action" feature, to where it could operate either in semi auto or pump action mode (in a similar manner to the Franchi SPAS 12). Additionally, Benelli has a whole line of pump action shotguns (the Nova series) which will share some commonality with the M1/M2/M3/M4 shotguns.
