You’re better off with pepper spray

I have one of these, they are a neat novelty, but i wouldn't trust it for anything, and it isn't that fun to shoot.

I love weird guns, but $300 seems like a ridiculous price, unless you happen to need a gun that folds into a rectangle.

The stainless steel NAA mini revolver weighs just 2/3 as much as the LifeCard, yet it holds more ammo, costs $50 less, and is built like a Swiss watch.

Or the Kel Tec P17: a genuinely practical, reliable, ergonomic, and accurate .22 under $200.
