The Colt catalog I picked up from their booth at the CMSA championships in Amarillo a few months ago has SAA's in it. It states that available options are 32/20, .38 Special, .38/40, .357 Mag, 44/40, and .45 Colt. This catalog has the 100 year highly engraved 1911 on the cover. It is really a wonderful catalog, with half the pages covering historical Colts. I don't know if it is still available but I'd recommend getting one if you can.
As an aside, I often ask Colt reps at shows if they are ever going to bring back the Python and they always say no. This time the guy told me that they had sold the Python tooling for scrap
However, today at Shotshow I saw some guys with Colts badges who told me they were there as guests of Colt, and they told me that they had been told Colt was going to be reintroducing the Python next year
