You're not going to find many revolver shooters at the two clubs in the Tucson area. Not sure about Phoenix, as I haven't been to a club match there in quite a while. I usually shoot single stack or revo here, and I'm typically the only revo shooter when I choose to shoot it. The majority shoot limited, production, and open. (Not necessarily in that order).
Your selection of revo attended matches in PHX will be better, and its not too long of a drive if you live on the Northwest side of Tucson.
There is a once a month ICORE match in Tucson and Phoenix (Maybe more in PHX). The ICORE state match, and the Western States Revo Match.
