[Single Six]

I feel safe in saying that the majority of physical confrontations don't warrant deadly force. For a citizen on the street, retreat should always be the first option, if at all possible. OC spray is for finishing a non-armed confrontation that you did not start. Your gun is your last-resort means for saving yourself or a third party from imminent deadly force. As has already been stated, the gun is an equalizer when used against an opponent who is also armed with a deadly weapon. OC spray is for those other, more statistically common assaults that don't involve deadly weapons. Since we don't know what kind of criminal assault may be inflicted upon us [if we knew it was coming, we'd make sure to be someplace else], I say it's best to carry both OC and your firearm.
