Don't sweat it, if someone does notice, be a good ambassador and use the opportunity to extol the positives of having an LTC.
I OC most of the time, that's changing with cooler weather, but most people never notice. It takes some time getting used to carrying, so just go with the flow. I have noticed several people CC but it's something I have trained myself to look for, starting as a LEO, and renewed as a LTC holder.
