1911's chambered for the 10mm cartridge can use a 9mm barrel. You may have to tweak the extractor, but with my Delta Elite it was not necessary.
You will need 9mm magazines and a weaker recoil spring. The breech face will be too large, and therefore a sloppy fit. It works, but I wouldn't trust it for serious use.
I have fired .38 Super, 9x19mm, 357 SIG, .40 S&W and 10mm from my Delta Elite.
