He already has the 2-barrel gun. Some folks don't like the pumping part. I recently wrote a chapter on guns for a new grouse book. ("A Passion for Grouse"). Looking at statistics from the Loyal Order of Dedicated Grouse Hunters (LODGH) concerning preference by gun type, early 1980's vs early 20-teens, pumps have dropped off significantly in popularity. As you point out, the problem isn't necessarily weight. The Ithaca English Ultra 37 weighed something under 5#, I believe . . . for those who can shoot a gun that light. But pumps just aren't as popular as they used to be.
