The article states specifically that people who commit suicide with a gun are more likely to do so if they own a handgun. IMO, that follows from the mechanics of the scenario.

It is easier to point a handgun at yourself and pull the trigger than it is to do so with a long gun. So, IMO, it is common sense that it is more likely that someone committing suicide by firearm chooses to do so with a handgun over a long gun, and they are more likely to do that if they own a handgun already.

However, it isn't like a random person who owns a gun is significantly more likely to complete a suicide attempt just because they own a gun. Yet, a person who is already at risk of suicide might have an increased risk if they own guns.

That being said, as a random individual, the risk of completed suicide over a lifetime is incredibly low, and that risk is even lower for suicide by any firearm.

I don't see this as being analogous to what I am saying. Maybe I am missing something.
