Have you read any of these? Some just aren't available online, although they are relentlessly cited. Of those that are, the data isn't always straight forward. Lots of proxies are used, and lots of citing of their* own work to support those proxies. Not saying I'm dismissing it outright, just that's its a tangled web.

Conclusions. Although our study cannot determine causation, we found that in areas where household firearm ownership rates were higher, a disproportionately large number of people died from homicide.

This is a chicken/egg type situation where they've chosen which came first but don't know why/can't support it. One could also conclude that in areas of disproportionately high homicide rates, household firearm ownership is increased.
