That’s accounted for. There’ve been lots of studies; here’s a story about one.

In particular, the researchers found, people who lived with handgun owners had a much higher rate of being fatally shot by a spouse or intimate partner. The vast majority of such victims, 84%, were women, they said.

Living with a handgun owner particularly increased the risk of being shot to death in a domestic violence incident, and it did not provide any protection against being killed at home by a stranger, the researchers found.

People who lived with handgun owners “did not experience such fatal [stranger] attacks at lower rates than their neighbors in gun-free homes”, the researchers wrote, noting that stranger homicides at home were “a small minority” of the homicides observed in the study.
