Just a reminder. . . .there is no law specifically against "brandishing" in Texas. There is a law against failure to conceal by a CHL unless in response to a threat of use of force/deadly force, or the actual use of force/deadly force. As fishman said, you felt threatened.

You did not draw your gun. You put your hand on it. I'm inclined to say that whether or not you "failed to conceal" is partially dependent on whether or not you were carrying IWB or OWB, and whether or not you exposed part of the gun in the process. If I rest my hand on my gun, but outside my shirt, did I "fail to conceal?" I don't think so. But it won't matter to the other guy because he's getting the same message. The fact that he did not back away but stood his ground and gave you the stink-eye even after you put your hand on the gun indicates at best a very disrespectful person, and at worst, someone with hostile intent. Personally, if I had to go as far as putting my hand on my gun, I'd have told him stop following me, stop crowding me, and to back away from my car. . . . .NOW!

In the future, if you have any doubts about it, be the FIRST one to call 911, and tell them exactly what happened, including your part, and that this guy is continuing to pester people in the parking lot. They'll send a cop over there to roust him.
