Found this site the other day:
It covers the legality and responsibility issues concerning CCW in AZ.
On a side note, you may want to save to disc, as it's 78 pages long.
Hope it helps.
And of course, I'll post anything I hear.. I get regular emails from DPS with all the new stuff. Most of it doesn't concern CCW holders, just instructors. But whatever does, I'll be sure to post it.
