At first we thought this pink Mace “gun” was ridiculous:

But it’s actually a very effective non lethal weapon, with a LED illumination sight and effective up to 25-30 feet away.  It has a built-in canister so you don’t have to reload.  There’s no kickback like there would be with a gun, and you can’t kill someone with it so there’s less danger of going to jail for defending yourself.  After watching this review of the gun, we’re much less likely to dismiss this pink “gun”.

Do you (or would you) carry a mace gun, or a real one?  If you were attacked on the street, what weapons or training would you have on hand to defend yourself?
