My mom’s the same way (she packs a .38 snubby, eyesight just starting to go) . She might hit your ear, she might hit your toe, she might gut-shoot you. Makes a good case for yelling: “Hello the house!” at the edge of the yard should one want to go onto her property. And I always call ahead.
She is in dire need of some Crimson Trace laser sighted gun grips. Buy her a pair for whatever holiday is coming up next.
