SxS slug guns seem to be relatively popular in Italy. I know that several makers list them, Bernadelli is another. My suspician is that since they are not rifles, the permits for them are easier to come by and given the popularity of driven boar shoots all over Europe, they are very effective.

But even given the above . . . they ain't Paradox guns! The old Paradox system was good out to 100 yards or more and still threw good patterns of shot. Their barrels were long enough to balance well in the hands for wingshooting, something that stubby 24" slug barrels simply are not. We're back to either one game or another instead of being ready for everything. At this point, a drilling is more available and makes more sense, unfortunately.
