Recommend you go over to Sixgunner.com and pose that question on the board or do a search. A lot of the SAA fans are over on that board and many of them carry the SAA concealed. They prefer the SAA as a CCW arm to any modern DA revolver or semi-auto. You can argue the merits of that all day long and I'm not going to, but there are quite a few folks who do it.
Also, John Taffin, the gun writer, may answer you personally. As noted above, he carries the SAA CCW routinely and generally prefers it. He also has a board at sixguns.com and you can probably reach him at either location.
I know to all the ninja warriors on this site, suggesting CCW with a Colt SAA or Ruger Blackhawk seems like heresy, but I've thought about doing it after I retire....
Good luck
