One of the things not usually considered on a high volume gun is overall weight. First thought would be that heavier would be better, to absorb recoil, but not so. Reasonable gunfit is more important than mass to reducing recoil related problems. The additional weight can become more of a hindrance than a benefit due to the effort expended each time the gun is lifted to the shoulder. I never noticed this at the end of a long day's shooting with my 20 SP II, but heard many others commenting on the strain of just mounting the gun. Most of these guys were shooting semi-jammamatic twelves. It can add up when you mount a gun thousands of times a day.

May God bless America and those who defend her.
