Hi Jeff,
IMO, most shooting in a home invasion or burglary situation is done at 10 feet or less. When speaking of accuracy how is the shotgun more accurate than the pistol? What is the diameter of the pellet spread at 10 feet?
Believe me, I have a shotgun and a pistol in my room and when hunkered down with all of my family in that room I will have the shotgun in my hands. so I'm not suggesting it is not an effective tool. I am saying that in some situations a pistol can be equally effective and potentially more effective in a home invasion scenrio.
When I mention more effective I am thinking of a veryclose quarters almost hand to hand situation.
