Smith & Wesson Holding Corp., the largest U.S. handgun maker, said it will begin selling shotguns in 2007 as the 154-year-old company enters a $350-million (U.S.) market. Two lines of Smith & Wesson shotguns -- fixed-action and semi-automatic -- will be introduced in January at a trade show in Orlando, Fla., the company said yesterday. Smith & Wesson said the market for rifles and shotguns is about $1-billion, or 60 per cent more than its traditional revolver and pistol market. The company began selling rifles in February. SWHC (Nasdaq) rose $1.09 to $13.39. Bloomberg
