    Designing a non-lethal OC selfdefense cartridge, please help.

    Nope, to be a firearm, it has to have gunpowder in that propellant, while this one has just a primer. Don't worry about the legal stuff, there already are such toys on the market, see "kimber guardian angel", "jpx jet protector" and a few more. What do you think about the materials that should...
