Being extremely familiar in OC deployment, I have been sprayed with, and consulted with longtime instructors of different types of OC, CN, and CS variations.
However, the one that I have found most effective, and have carried, and used for almost five years now, is the MK-4 ballistic stream from DEF-TEC.
I have seen it work on almost every person, (-1) and animal, (except badgers
) and have never had a problem. (Just don't spray it into a 30mph wind after a foot pursuit.)
Don't listen to all the talk about SHU's because it doesn't account for a whole lot. Its just mostly numbers so certain companies can entice you to buy their product. (Mine's Bigger Than Yours Theory
)
The real general rule for OC is, "No Pain, No Gain". For the
most part, your hoping on a physical reaction to the spray, as opposed to psychological. If they're
too, "doped up", or drunk to feel pain, chances are, its just going to piss em off.
Personally, if your lookin for good sprays, stick with OC, (the ones that have food-grade ingrediants), and avoid the others with harsh chemicals. Easier decontamination if you have an "accidental emmission".
