Ive loaned them to family. - - The guns I've loaned out were good, solid working guns. Rifles and shotguns for hunting and defense. I guess I'm the 'gun guy' in my circle of family & friends. The others are hunters, but not really 'gun nuts' - - they see them as tools. I don't loan out the more fancy or rare pieces, but let others shoot them when I'm there with them. For some uses, its great to have a synthetic stocked 870 pump gun or Benelli auto that you can use hard and not be concerned about getting in the muck. My buddies say they enjoy shooting my 'fancy guns' but wouldnt want them because theyd worry about messing them up and losing value.
I've never loaned out a handgun though.
