Closest I've ever come was when I was driving a wheelchair van. We had customers in Detroit, so I made sure I carried whenever I went down there. One cold, rainy, early spring morning, I pulled up to a customer's house, climbed out of the van. A woman in a car across the street rolled down the window, said "Be careful, there's a pit bull on the other side of your truck." I unsnapped my jacket. Then she said, "Here it comes!" I had my hand on the grip of my M&P 9c, ready to draw. About this time, the dog appeared. He had a pitiful look that said, "I won't hurt you. Please take me somewhere warm and dry." I came this close, (index finger and thumb barely apart), to taking him home, but he had a collar on, he belonged to someone. So, that was that. Haven't come close since.
