Timothy,

Does not limit my choices at all. I buy guns to hunt with, and that means swivels and lightweight slings are essential, as are lightweight hammer doubles. Hunting includes desert quail, turkeys, grouse, bandtails, ducks, geese. All except ducks and geese require extensive walking, with best duck hunting requiring 2-3 km walk to hunting area. ALL my hunting shotguns are Merkels, Sauers, Husqvarnas, Brownings, Carl Stegelis -- all totally reliable, deadly bird killers and clay busters, all with factory swivels (save Browning made for USA market, to which swivels were added immediately). Never had any reason to bother with USA or Brit guns.
