Even the EFK site shows them on back order. About all they have in stocks for anything FN is FNS compact and 509 barrels. They won't even let me back order 9mm conversion barrels. All I get is "notify when back in stock." I've been meaning to email them but am seldomly on my computer during the week, and I hate typing out lengthy things on my tablet. I honestly don't know how responsive they are with email though, as I've never done business with them before.
