I don't really have that hard of a time selling certain guns. As my taste and interests change so does my collection. Those that I am more "attached" to I would find very difficult selling even if I was in financial difficulty. I'd probably look for other ways to cover the costs. I do feel a slight remorse for certain ones like the fact that I sold my first gun ever a while ago but the feeling passes and I move on. All I have to do is open up the safe and I'm happy again.
