Do you take trade ins and/or purchase firearms?

Yes they do.

Yes they do, but don't plan on getting what you think it's worth....worse than trading on a car. They'll give you roughly wholesale value, but at least it's convenient for an upgrade.

Yee, they buy used and trade. Ive traded multiple pistols with shoot straight. All proceeds i used towards a new gun.

sell for money or towards new purchase

They sell used guns . So I would call but the pawnshop is a sure thing

No they do not. Your best bet would be a pawn shop.
