The 20 is built on a "O" frame and the 28 is no a "OO" frame. There is no difference in measurments between the two except at the width of the fences(narrower for the 28), and the "OO" is made lighter by milling out grooves in the watertable.
I double the 20ga barrels safely be set as close together as the 28ga barrels.
