One of the NRA Executives won a Darwin Award a while back. Got into a domestic dispute with his wife. 

She made it to his always loaded "self defence" handgun before he did, and shot him dead. 

The most common gunshot death scenario (80%) in both Canada and the USA is Suicide, followed by Domestic Homicide and quickly escalating Personal Disputes where one or both parties have fast access to loaded firearms. Use of firearms in other crimes is a distant 3rd gunshot death scenario.
