Never "pulled" mine, but glad I had it on a couple occaisions.
Once on my way home from wally world, I saw a guy who didnt belong in my neighborhood walking in the direction away from my old apt as I turned onto my street. As i was carrying in my groceries, I noticed he had changed directions and coming my way, he got about 30 feet from me and said "lemmie ask you a question". I just slipped my hand under my shirt and got ready to draw. When that happened, the dude just turned around and kept steppin....I know, I know..I should have gone inside and hide like a good little "sheep", but I never saw that fella again. Wonder if he thought twice about approaching a stranger in the dark again!
Second was a possible robbery in a parking lot. There was an old man ride up to the Perkins restaraunt on a bike after it was closed. ( I was in the truck with a date
) The man had something behind his back and was trying to get the waitresses to open the door. It was either a machatte or a big feather. I couldnt really tell. I just got a cell phone ready. There wasnt anything close to a good shot. But glad I was armed.
