I just purchased a SIG Sauer 1911 Traditional Match Elite Stainless 9mm Pistol.  I really wanted the .45ACP version, but I'm consolidating my ammunition choices (still may get one later)!  Anyway, I'm not too crazy about the ambi-safety and was curious if I could replace it with a Wilson or Baer?  The frame should be the same, yes?  Thank you for any input.

Disregard.  Found some information and beside the external extractor, all parts are compatible.
