Hello all...as someone who uses a double exclusively for waterfowl, I could see tri barrel gun being very useful, especially when one has to chase down cripple goldeneye ducks. The weight would keep the recoil from 3" shells from battering the shooter. Assuming it has auto selective ejectors, one could keep steel 7's in one barrel for the inevitable coup de gra(sp?) and your heavy shells in the other 2 barrels.

All sorts of possibilities here.
