Guns: The number of gun owners in the United states is 80,000,000. (yes, that's 80 million) The number of accidental gun deaths per year, all age groups, is 1,500. The number of accidental deaths per gun owner is .00018. (Statistics courtesy of the FBI).
So, statistically, Doctors are approximately 9,000 times more dangerous than gun owners. Remember, Guns don't kill people, Doctors do.
