Dave,
When I said unnecessary stress I was talking about the return stroke to bring the bolt back into battery. Certainly, a pump shotgun will need a good pull to eject the spent round as the casing has expanded in the chamber and provides a lot of drag. The problem is when the forearm is moved forward.
The force from the weight and momentum of the entire shotgun that has been propelled rearward (downward) by the pulling action and gravity that the forearm (i.e., action bars) sees at its fullest forward position is a heck of a lot more than if you were to slide it forward in the normal way. I wonder how long a Maverick would last with its one bar compared to Mossberg's two.
But, as I said, it's his gun. I just hate to see people unnecessarily abuse their firearms, cars, knives, etc.
