Making them, and marketing them in the USA, is two different things. As I recall, there were samples of RIA/Armscor 9mm 1911's at last year's Shot Show, but I've never heard of them actually hitting the stores here yet. Seems odd, because there's a LOT of people waiting for them to. Kinda like the High Point .45 carbine. Armscor branded pistols aren't marketed in the US, as far as I know, but Armscor manufactured guns are sold here under several other names, including RIA.
I have three RIA 1911's in .45, and would definitely buy one in 9mm, if I ever see one.
