One way you can do it is go with a shop with FFL that has a account with ie. Gunbroker they usually charge a fee $60 or so. Takes all that out of your hands. Just my 2 cents,something to consider. Them model 37`s are nice.Good luck
this would be the way to sell it with the least amount of headaches on your end, I think if your selling gun broker would get you the most money.
Good quality pictures on gun broker make or break the deal, ask to see some of the current guns for sale that your ffl has listed so you can see the detail and quality of his pictures.
