Ive been sprayed twice with pepper spray while a LEO. I lived for many years in bush Alaska, and Ive killed grizzly bear. I currently work summers in Montana riding horseback in the back country, and I wont let people around me or my horses with pepper spray. If you set off a can of that stuff inside of a tent without ventilation, it could very well kill you if you have any respiratory / heart issues. Human OC spray that incapacitated those 6 cops mentioned above is 5% pepper. Bear spray is 10%, and the canister holds a whole lot more. I now carry a full size 1911 .460 Rowland loaded with BB hardcast with a Surefire slung from the bottom to back up my Winchester 1886 saddle gun in .45/70. You cant shoot pepper spray into the wind, you can a gun. Pepper spray is mostly useless in a torrential downpour, a firearm isnt. You cant reload a can of pepper spray, you can your firearm. These are just my own observations from my own experiences. Yours may be different, and Im sure just as worthy of consideration
