What gophert said...... YES YES & YES!!
I would almost let my 115lb 12 year old son shoot my gun now with 3.5" shells. It reduces the kick that much! I really couldn't believe it when I shot it for the first couple of times with that stock. Now instead of crying like a little school girl after 3 shots with my old super cell pad, I can shoot many shots and still use my arm the next day!
