I've been stopped many times over the years and almost every time I was OC, with my firearm in a belt holster. Not once did it cause any problems. The few times I had problems was when the gun was on the seat, those problems were years ago. I don't think the law is the slightest bit vague. Only the very uninformed or authoritarian LEO will claim an uncovered handgun in a belt holster, in a vehicle is concealed. The last time, I was stopped by an Anderson Co. Deputy Sheriff. He asked if there were any weapons in the car. I told him yes and he asked where. I told him on my right hip. He said OK, took my DL to his car, came back, handed my DL back and said "watch your speed" and walked off. He never did see it or ask to see it.
