I find the 7 1/2 - 8lb waterfowling 12s with 30 or 32 inch barrel to be just right.
32 inch with a splinter are a little long for me. Don’t really care for beaver tail forends.

But I like the semi pistol grip they typically come with, and with a decent recoil pad, you can shoot 200, one ounce cartridges in a day without misery. I prefer extractors on the range.

Out there doing it best I can.
