Another interesting stat from that article I linked is that among those that have committed DV, those that also own firearms tended to be more violent and more likely to use any weapon, even if their firearm wasn't actually involved in the incident(s). The article stops short of trying to draw any inferences from that statistic (as it should, since that's outside of its scope), but I'd interpret that as indicating that owning a firearm emboldens those that are inclined to do violence to go further than they otherwise would (which is also consistent with the statistical reality that firearm owners are more likely to be killed by gun violence).

Translated to the issue of DV homicide during a restraining order, it stands to reason that restricting the culprit's access to firearms reduces all homicide rates because the culprit generally feels less confident about enacting further violence. That's speculation, of course, but it seems consistent with the stats.
