One of the issues with saps is they are generally 'soft' or with the lead mounted on a spring, so all you can really do with them is hit. I also have in my pile of ""stuff" a slapper, wich is a stiff sap than can be used to prod someone. I never carried that either.
And in AZ, it is a 'concealed weapon permit', no firearms listed. In theory, I could carry a Thompson subgun under my coat and be legal. We regulate the person, not the tool.
