Yeah that's why they discontinued them. They are almost unbareable to shoot. The way over-unders are balanced, the bottom barrel is okay to shoot the heavy load because it is more in line with your shoulder, but the top barrel is above level of your shoulder, so it causes them to jump considerably and thus, quite painful. No way I would use 3 1/2's thru a double for ducks. Too much recoil too many times in one day.
But if you want it to use for turkey also, then I would understand.
