Use what you have but only if you practice with it.
Kimber has a interesting two shot pepper spray gun that fires two blasts. The best part of the
Pepperblaster Gun is kimber offeres the
Pepperblaster trainer which fires dye and you would use it to practice and the
Pepperblaster demonstration which allows you to repeatedly use for practice.
On another note:
I had to go to the County Court House while in the Philly area while visiting the area for Christmas this year. As of 2-3 years ago Pennsylvania passed a law that you were not allowed to enter a Court House carrying any kind of weapon anymore. Before that you were allowed but you had to leave it at a "coat check" (Gun Check) window.
Anyhow my wife and I left our cutlery, mags and handguns in the car before we entered the Court House. Even without the hardware the metal detector kept dinging as I repeatedly went through. So I was taken over to the side and "wanded." While the bored police officer was wanding me I noticed a weird looking gun on his belt. I pointed to it and asked him what it was and he replied, "A taser."
I replied, "A TASER? Good God."
"Yeah." He said, "They took away our pepper spray and issued us a taser."
MrsMac at this point had her arms crossed, was tapping her foot and giving me "stinky-eye" so I didn't quiz him why the change from pepper spray to the taser was made; However I suspect the taser was more affective.
I know that some folks carry pepper spray while in the woods for bears. I have also heard that a angry mom will only be slightly discouraged by pepper spray and again you have to practice. Here is one of many posts on the internet about using
pepper spray on bears.
