SxS shotgun barrel were sighted in to cross each other at a certain range, due to the wide sight plain. The reason I doubt you'll see the O/U is because of price. Most weapons in the west were used not because of there power or accuracy, but rather their price. Most people were still packing C&B in the territories in the late 1800's. In the early 1900's, wealthier folks would have been moving west, so it's possible that they ended up out there in this game's time frame, but the fact of the matter is: it adds nothing to the game's balance or gameplay.
