I never bought a 21 with the idea of selling it for a profit. However, my friends who are not "gun shoppers" seem to appreciate my taste in guns and end up owning what I thought were my lifetime acquisitions. I don't remember ever selling one to a stranger. Now that I rethink my figures, fifty may be a bit high. I may honestly estimate that 25 or 30 may be more to the point. I would buy any of them back for what I sold them for, or more.
