I don't remember ever firing a benelli. But I do remember one time I fired a bottom eject 12 ga that seemed to kick too hard for the loads that were in it.
I've heard people complain about the old browning humpback for several reasons...too heavy, whacks your shoulder too hard and cycles too slow.
But I personally never noticed any discomfort from it in either way, although it is a bit slow, but so are all auto shotguns. It's one of my favorite shotguns. I like auto fives alot. In fact, it's happens to be the only auto shotgun that I like at all. My opinion is that there are two kinds of shotguns, slow and fast. autos are slow, and everything else is fast. So when I hear someone complain about a slow cycling auto, it just doesn't make sense to me. If you want fast, get a pump or a double.
My Remington 1100 Combat Master cycles faster than I can shoot it.
