Bart Skelton relays a sad tale at handgunsmag.com of trading away a rare Winchester 1894 rifle for a nice, but decidedly less valuable, Colt single action revolver. It was a half-octagon, half-round barrel takedown gun with a special order front sight that he’d lovingly restored after rescuing it at an auction. One friend lives by the mantra that you never sell (or trade) a gun. Ever. That’s one way of avoiding seller’s remorse, but most of us have developed a hankering for something shiny that we just have to have, only to repent at leisure. So ‘fess up. What’s the worst gun deal you ever made?
