I don't know how much the popularity of SxSs has changed but I do know they are lower profile now than a few years ago. I picked up a Shooting Sportsman
man from 2005 awhile back and it was loaded with full page color adds from all the Spanish Makers, Merkel, Verney-Carron and Double gun dealers around the country. Stories were about SxS restoration and repairs. Much of the hunting was done with SxSs. Now its mostly Italian O/Us and unaffordable hunts. On TV There were shows about hunting with SxSs and repairs and restoration of SxSs. Now hunting TV is canned Deer and Hog hunts. They must be easier to film than Chuckers or Grouse with a pointing dog.

It was a good time to build a SxS business. You could sell anything sound with 2 barrels. When the popularity in print and TV faded the entry-level (boxlock extractor 12ga) market faded.

The popularity of SxS shoots is strong. The mid-west lost a few but not from lack of popularity. New well run shoots are doing well.
