You're probably aware that you can sell to someone out-of-state which involves you going to a nearby local gun shop and letting them ship to an out-of-state FFL. And the approx. charge is $25 + whatever it costs to insure and ship.
I'll give you $400 ($50 more than you're asking) and I will cover both the shipping and FFL charge on your end. I would still have to pay an FFL on my end to receive it and do the paperwork.
Let me know if you're interested in working with me. I'm looking hard for one of these so don't wait too long to decide if you want to sell it to me with the above conditions.
