That's exactly how they should be designed Stan.

It's remarkable given the common way of gripping the forend of a SxS gun that a button protruding in the location they do was ever considered acceptable.

O/U guns are generally gripped differently (although I've seen some unconventional shooting styles) so the position of the button is less of a concern.
