Well, I like 1100s, but I have 5, and ten barrels, so I don't need an 11-87. If I was starting out with one gun and wanted to shoot 2-3/4" and 3", I would go for an 11-87.
Yes, I shot 3" with the standard receiver.
I don't like the full priced Benellis, so I probably wouldn't like a cheaper version. They do work. They can be fussy with light loads. Without a two piece stock or the like, they can knock your fillings out of your teeth with stout loads. Now all the Benelli fans can come in and give us a lesson that it's all in the fit of the gun. All inertia gun lovers have that down pat.
