Emballmer883, I wish you luck with your recovery from the amputation. I wonder if you could setup a prosthetic with self contained shooting sticks or built in gun rest.

Lack of trust could be related to unfamiliarity with the capabilities of hunting pistols, wanting to avoid the spray and pray shooters, or not wanting folks out in the field with something that is arguably easier to shot yourself with. I think that arranging some range time would go a long ways towards educating your uncle.
