From the nothing-is-as-easy-as-it-appears department, I'd like to fit two euro game guns with Galco and/or Gamekeeper slip-on recoil pads.

One gun's butt dimensions are 5 1/4" X 1 1/8"

The other gun measures 5 1/8" X 1 1/8" at the butt.

Which size Galco and Gamekeeper pad will fit each gun?

Thank you
