Its only misleading if you are not capable of realizing a person can shoot themselves or another person.

Calling it simply a firearm means that a firearm caused the death.

Thats it.

If you automatically read context into that, context that is not there, that's either a you problem or a literacy problem.

Over the course of five decades, the data showed that the strongest association between an increase in homicide rates and elevated suicide risk occurred in rural communities and among white populations. A one-point increase in the overall homicide rate correlated to a 3.6 percent increase in the suicide rate the following year, according to the study. The correlation was even more stark between firearm-related deaths: For every one-point rise in the firearm homicide rate, there was a 5.7 percent increase in firearm suicides.

tl:dr, firearm homicide and suicide rates are well corellated with a time lag.

We can say that a big problem is simply too much access to too many guns and say that with data as well.

“These results would suggest violence prevention is suicide prevention, and that we can reduce suicides by reducing violence in local communities.”

“We know that suicide and homicide in some ways have a lot of the same drivers,” said Dr. Emmy Betz, an emergency physician and public health scholar at the University of Colorado who specializes in firearm suicide prevention. “Poverty, lack of access to reliable housing or food, relationship stressors, and domestic violence can all increase the risk of suicide or homicide.”

The... so obvious it hopefully doesn't have to be stated... but apparently it actually does... part, being:

It is significantly easier to kill either yourself or another person with a firearm, than without one.

Its even easier than via using a car, in the US.

Plenty of people kill themselves and others in car accidents or otherwise using/involving a car... but the above graph is as agnostic to intent, to victim/perpetrator with cars as it is with guns, but for some reason, you don't bring that up, that doesn't need to be specifically clarified.
