RE: Toughest Auto shotgun
I would say either the Benneli or the Berreta would be exactly what you are looking for. As for the M-1100 fans, sorry, but I have had more 1100' s come thru the shop for repairs in the past 12 years, than all the other shotguns I have worked on combined. I have yet to have a Berretta or Benneli come in for any other reason than for a good cleaning.
