I like to have my fun with them and move on. Sure, I have a core group of firearms that I would never think about selling. Most others are common and replaceable and have no fond memories attached to them. Tastes change and im not going to hold onto something just because I thought it was the bees knees 20 years ago or 3 months ago. Sometimes, the grass is greener on the other side. Life is too short to regret all the little stuff IMO.
