I'm in a major city in TX.  I don't OC, simply because I prefer to stay low key.  I find a loose fitting shirt over my hip holster fights the heat effectively and allows me to maintain a subdued posture.  I have my lady and 3-4 kids.  If you're targeted in advance, it adds a litany of BS to the already bad situation. Plain and simple, you can't draw on a drawn weapon.  Best bet is to appear "normie" adjust as needed, then engage. I routinely carry, my assisted opening knife from Iraq, sidearm with 3ea 15rs mags and one chambered, OC spray and a light in dark hours.  My teens carry OC daily.   I have trained them; discussed mental preparation, open hand tactics, de-escalation (and when to recognize that it has failed or is not an option), and solid strategies to outsmart a perp.  I.E. having "home field advantage" and using familiar surroundings to gain the upper hand. All things that are actually simple common sense.  Stay safe brethren and patriots.
