Sliver, I agree with you that there is no "logic" in having to operate an additional
lever/button to fire a third barrel that does the same as the other two (chokes aside).

Maybe, as you say it was built on a drilling action. Otherwise an internal inspection is
in order.

Very nice gun and cool cocking indicators btw.
