I’m lucky enough to live in a state that (at least for now) hasn’t had gun laws too trampled by libtards, so it is rather easy to buy and sell. I know what you mean about not wanting to get rid of them. Most of mine have no historical significance, but have time and dough put into making them just so. Sometimes they are a bit hard to let go of, but I tell myself that if I miss one that bad I can always get another. Maybe I have to look for a while to find a deal, but can just about always get close to what I had.
I had an earlier model Iver Johnson Thrasher SS, the stainless finished ones, before they started chroming them. I polished the slide, put grips on it, bought a nice holster, carried it a while then sold it. Few years later bought it back from a different guy than who I sold it to, and bought it back for less than I had sold it for. I then put night sights on it, polished the frame, trigger, etc. Shot it a bit then sold it again during a “purge”. I keep my eyes peeled for it and will own it again hopefully one day. Hopefully for less than I had sold it for! : )
