The PPC9 and Super 9 both use double stack magazines and are available with 5 inch barrels. Both are basically match 5906s, and are Single Action Only. Both are rather rare, too.
The Super 9 came with 9mm, 356TSW, and 9x21 barrels and was primarily sold overseas, but a few examples are available stateside. The PPC9 was available with either a 5 or 6 inch barrel, but was only sold to LEOs to use in Police Pistol Combat matches.
If you find one, expect to pay between $1000 and $2000.
Super 9
6" PPC 9
The Performance Center was able to custom make double stack 9mm guns with the longer barrel. There may be a handful of custom 5" 59XXs floating around out there for sale. Not sure if you could still order one straight from S&W, though.
