As a Benelli owner/lover (SBE) I would consider porting sacrilege. I don't know the actual # but recoil of a 1 1/8 target load is very low. If you want to customise your weapon I would highly suggest [link]http://www.benelliusa.com/firearms/m1.tpl[/link] you have every FACTORY option you could want. shorter /longer barrels/magazines...the list goes on. Hopefully you got the synthetic and could go with the recoil reducer that fits in your stock.
