a Nasty divorce, domestic situation etc ?
The introduction of a gun at this time might not be a good idea for someone with nu gun experience ? How is her relationship with her x-husband ? Does he have visitation rights and come to pick up the kids ? Is he the one she needs protection from ?
I would strongly suggest a course in fire arms and self defense before giving her a gun. A gun in the hands of an inexperienced person could lead to a bad situation especially with children in the home. Could lead to the wrong person being shot, the gun could be taken from her and used to shoot her.
My suggestion would be to have her get training before giving her a gun.
