Never been drawn on.

Brandished once.
Old man kept harassing me and made threats of bodily injury, (I was parked at the RTD park and ride waiting for my wife with my headlights on that were to bright for him). He left the scene and called PD. PD Showed up and I explained my side. PD left to have a chat with the other fellow.

Never pointed at anyone.
Thought I might have to at Wal Mart a couple weekends back though. Lady nearly ran over my toes as the family and I crossed into the entrance to the store. I yelled loudly at her, she went up a few isles turned around and came back for a 2nd shot at us. Screaming and yelling out of the window! Obviously we didn't give her another try. She proceeded to scream and yell as she went racing through the lot again...
