If I were you I'd think about taking Garretson's to small claims court.
Garretson's broke no laws in selling me the gun. They are not required to, and have no way to check to see if a gun is stolen when they take it in on trade. I've talked to a lot of gun dealers lately and none of them check since the ATF has not set up an easy way for them to run serial numbers. They all figure it is not their problem.
