Is that supposed to be funny?
Yes and no.
While it (pepper spray) is better than nothing it is not anything upon which I would depend.
When I was in the service I was always amazed at the number of troops that easily 'survived' the CS chamber. Probably in the 5-7% range that the stuff barely affected.
That Taurus a few posts up is "The Judge" it can be loaded with either 45 colt (long colt) or .410 in any combination in the 5 chambers. The 4inch model only weighs 29 oz and it is not expensive, GREAT choice for home / car defense.
