I'm not well versed in AZ law but their rules on open carry seem quite odd...
"The law states that as long as a portion of the holster
is visible, the weapon is not concealed. It is recommended that at least 2-3 inches of the holster be visible."
"An unholstered handgun carried by a non-permitee which is only partially visible is considered concealed, hence the recommendation to keep carried handguns holstered."
I almost want to say that a clipdraw could be constued as concealed (IANAL). Another question for you that I have been debating with some coworkers about.....Why would you choose to carry a gun without a round in the chamber?
