yes the 22LR 1911 xchange fits (full and carry not ultra). Sig doesn't list 1911 xchange any longer on the USA site.
I haven't seen a 9mm 1911 xchange, would be nice i'd buy one today to avoid a pistol permit, paperwork, ffl transfer, nics wait and other delays.
Also cant can't confirm the 22LR xchange fits the 40/9mm 1911 models.
EDIT - the shorter 22 mags will annoy you a little however with the tacops longer magwell grips (same as my emp scorp).
