I use to think along the lines of I would never sell one. Now that I have gotten older I realized that I would never shoot some of them again and have no desire to own them anymore so I started to sell them off slowly. Some I have been able to sell and the others I have traded. The ones I for sure won't sell are my 45 colt revolvers. I am going up in quality and less quantity. There is one that I would sell to only one person if they asked, if anyone else asked it would not be for sale. My dad has only gotten rid of maybe three guns that I know of in the last 20 years and two of them have been to me. He would rather have them sit in the gun safe.
