As of my last update in October 2023, there have been no widely reported recalls specifically for Benelli shotguns. However, it's always advisable to check the official Benelli website or the Consumer Product Safety Commission (CPSC) for the most current information on recalls. Additionally, contacting your local dealer can provide guidance on any potential safety issues.
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.
