I can't imagine ever selling a gun. I spend **LOTS** of time researching a weapon before I buy it, so I can't imagine turning around and selling it. I suppose if were giving me major problems I'd think about it, but then again I only buy guns that come with a lifetime warranty so I don't see that being a problem.
Another thing is I will never buy a used gun. Not sure if I have a good reason for it, other than I don't want to buy someone else's problem child.
I'm hoping to be able to pass all of my guns down to the next generation--
