Out of curiosity, what gun, or guns, do you never shoot but just can't bear to part with. My list is embarrassingly long, so won't bore you with the total, but I have a Colt 1911 that Bill Wilson modified for me years ago before he started manufacturing guns, that I used for Combat Matches (early days of Practical Pistol Shooting matches), that I won with a lot. I also have a .38 special S&W 3" bbl that I bought for my wife before I was shipped out to Viet Nam, for personal protection at home. This was 1967. I also have a Hi Standard .22 Magnum Derringer that I carried over seas, that I simply keep in the safe now, and can't see ever having a use for it or carrying it today. But it certainly went a lot of places with me back then in SE Asia.
