M1S90 recoil-reducer and pad

[alta]

Hi,I,m the proud owner of a new M1S90-18,5 barrel,open rifle sights-3 chokes.what a versital gun,but I encountered a few problems with add ons.!st,let me add,syn stock,non pistal grip,but different from the sporting model,as the carrry strap plate goes side ways thru the stock,for right,or left side mounting,not on the bottem.I went to install the benelli recoil reducer tube,but inside the stock is a support,that will not allow the tube to contact the threads it screws ontoo. oh well,I dont think the skinyer tube would work,way too long.Next-ok I deal with the pad,but using the limbsaver web site,and looking at my ownners manual,it appears again ,the sport,and ,what benelli calls the combat model,are different.Its easy to see the grip checkering diference,but also,the combat version is very hollowed out,with only 2 small bosses for the mount screws.I dont think they have a pad to fit it.I,l post more on possible fixes,but 1st,has any one else encountered this?
