C2 Taser with Integrated Laser Sight
I've been looking into tasers for awhile now, and this one keeps coming out on top for ease of use, portability and reliability. I'm not sure I would be able to fire a gun at someone - even if my life was in danger, I think I'd be too afraid I'd miss and hit someone else. A taser seems the next best option, and this model is described as having "a higher instant incapacitation rate than a 9mm Hand gun." It gives you that time you'll need to get away, without all the worries that can come with carrying a gun. Although I hope to never need to actually use it, if that is necessary sending a copy of the police report to the company gets you a free replacement. So leave it at the scene and get outta there if you do need it!
