Actually I'm not to concern with this. Both my wife and I have our affairs for end of life taken care of and there is an envelope in there with what and who I want to have each weapon and accessories to go to.
But then, when it happens, I really don't care. It might sound childish, but I won't be here and I'm not going to worry about something I will have no interaction about. If she lives longer than I, she will do what she wants, ... either following my instructions or not. So I don't care.
But until then, they are mine and they will be with me until I have no control over it.
