Since you didn't respond to me this is only for discussion and not argument... Firearms are like underwear and are very personal. I get that.
Sure they could have done that but what about the folks who wouldn't want it? There are ways to bring the upper pic' rail down to where it's accessible who want that and keep the pump handle feeling normal and smooth, like a shotgun for all others.
Personally I have no problem with it as it exists, but my mind is open to arguments, and I know that nothing fits everybody. I also know that I didn't change the pump handle but brought the pic rail down to my pump handle hand.
