From Arizona.
ARIZONA: Legal.
Section 13-3101.7 excludes from the definition of "prohibited weapon" "**any propellant (or) propellant actuated devices ** which are manufactured, imported or distributed for their intended purposes **". There is nothing that appears to regulate or prohibit the lawful use of self-defense sprays of any kind.
I'd be careful about declaring bear spray legal.
What you quoted says, "for their intended purposes." The intended purpose of bear spray is to be used on bears, not humans. I think you could find yourself in a world of trouble with that clause.
Besides, I used to sell bear spray. Most of them don't come in a nice little discreet package. They are pretty big canisters. Nothing I would want to try to tote around along with everything else.
If you want more spray they do have larger canisters of human spray. I sold one the size of a fire extinguisher to a bouncer who had to use six small cans to break up a group fight. But we were sure to make sure it was for humans.
Lawyers can be picky about that kind of stuff.
My question would be, why do you feel you need to have that much/kind of spray?
Personally, I carry the Kimber LifeAct. I haven't had to use it but I've watched some videos of different sprays and I like the fact that it is a gel that is "fired" rather than just a spray under pressure. I'm comfortable with it.
The only drawback is that it only has two shots, but it's sleek and small and fits wherever I need it to.
