I can't shoot a gun with only 2" at the heel well in the field, pre-mounted at clays is not problem for me but guns that high I struggle to mount quickly. My gun is 1&3/8" x 2&3/8" and it fits me very well. I can shoot 1&1/2" x 2&1/2" without a problem and that is what I consider to be standard modern dimensions for a game gun. Different strokes for different folks or different horses for different courses, either way, find what works for you.

I think one of the biggest factors in fit is indeed drop and the sight picture that your brain expects to see, I float my birds and always have and never could shoot well with guns with lots of drop, my father is exactly the opposite. I have read Stan's comments on how he likes his guns to pattern, it would not work for me but it does for him.
