My HH6 is not a gun person.
She knows I have guns, she knows where I keep them , but she has no idea of their value. She knows when I buy new ones - mostly She just doesn’t keep track of them or the stuff I put on them - optics, lights, slings, etc...
I have two friends that I trust very much. They are both colleagues, both gun guys, and both are people that I shoot with regularly.
They both have a running list of what I have including types, descriptions, and serial numbers, along with the combos to all of my security measures. A third list is kept in the family document safe so HH6 has it too. Her copy also has a reminder to contact those guys ASAP to start handling everything.
God forbid something ever happens to me, they have instructions to keep certain guns for my son, to pick one out for themselves, and to sell the rest for HH6 so she doesn’t have to worry about it. This process is also documented in my will.
Most importantly, they are charged with teaching my son to shoot, to appreciate his 2nd amendment rights, and to be a good man.
I have similar lists from them for the same reasons.
