Don't know about that:
Research published in the New England Journal of Medicine found that living in a home where there are guns increased risk of homicide by 40 to 170% and the risk of suicide by 90 to 460%.4

The risk of dying from an unintentional gunshot injury is 3.7 times higher for adults living in homes with guns, with handguns in the home posing a particular threat.5

On a state-wide level, states with higher rates of household firearm ownership have been shown to have significantly higher homicide victimization rates.6
