Many retailers get incentives for meeting sales goals from manufacturers that they act as certified dealers for, which means it costs them more money to sell your used S&W to another customer than it would to sell a new one. Locally, we have a shop that does have a small amount of new inventory but their bread and butter is consignments and transfers. I’d look for a place like that. End of day though, if I really didn’t want the gun, I’d take what I could get from the lgs s before I’d sell to someone I don’t know and risk civil or criminal liability if someone did something stupid with it.
