I just purchased a M2 20 gauge as my do all shotgun. Seeing nothing really is a do all I'm looking to add a Magazine Tube but finding that Benelli doesn't offer one for the 20 gauge. Any recommendations as I'm new to shotguns, currently a 3+1 but want to add 2 more shells. I'm primarily using it for range shooting and home defence, Looks like I should have held out for a 12 gauge as their are more options but couldn't find one anywhere. I do like the 20 because of the lower recoil. thanks in advance
