I vote you find her some .380 ammo....soon.
My Grandmother lived about 4 miles from town. Into her 90's, she used to sleep with a 32 automatic under the pillow.
Get her the ammo.
You may be able to find some on Gunbroker.com, but you'll probably pay through the nose for it. But, I know someone that might trade you some for 209 shotgun primers. PM me.
