My father carries a Iver Johnson double action pistol in .22 caliber. Its a very small pistol. A pocket pistol if you want to call it that. Its loaded with .22 hollow point Winchester bullets. The pistol holds eight rounds I believe and after you fire the first one simply by pulling the trigger, the rest are single action as the pistol is then cocked. On his last visit to my place he brought that little pistol. Out to 7 yards he was hitting a brown grocery sack more in the center of it then in the edges. And he was firing fast. As he said.. I'd only pull it if I had no other choice. And then I would shoot to kill them. Personally I couldn't think of any one that would want eight of them hollow point hornets hitting them in center mass. It would make for a very bad day.
