I contacted Gemtec, Stormlake, and a few other manufacturers to find a threaded barrel for my XDS-4.0 .45 - and all said no plans.... Then I received this, yesterday from Bar-Sto: "Jeremy, thank you for contacting us, unfortunately we have not yet begun production on the XD-S line from Springfield Armory. We do have plans to make them and we should start seeing them soon, but I really don't have a solid tentative date at this time.

They are coming!!!!
