Be careful putting too much stock in websites like that one, which states that "...a bullet...is a tool..." I was researching the Bullet Button a few days ago, and went to the CA DOJ website. Did a search there and came up with a new ruling from DOJ that a bullet or cartridge IS NOT considered a tool, thereby making the Bullet Button (or anything similar) unapproved in CA.

Sorry that I can not cut and paste that info, for some reason I can't get the page to come up tonight (probably the 40+ mph winds and my aircard not being compatable)...
