Handgun suicides kill over 20,000 Americans a year.
And these are right wing, pro gun Americans for the most part. It's in the interest of the pro gun crowd to save these people.
The thing about handguns is once you pull the trigger and splatter your brains all over the head liner of your Ford F150, you're almost guaranteed to die. A shot to the head is very lethal.
Another bad thing about handgun suicides is that it's quick and can be done in about 5 seconds time. Hanging yourself takes a lot longer and in that time you might decide to put your suicide off for a few days.
