Harry's first meeting with Nicodemus is actually a great example of a situation almost identical to this one. NPC-cameo-of-the-moment empties a pistol into him from only a meter or two away. She doesn't miss a single shot. Spots of blood bloom on his chest. He stands, annoyed, remarks on her lack of manners, and then, as she continues to fire, motions for her to hurry things along, because he has business to take care of, and her shooting him is just downright annoying. But not threatening.
