I searched the forum for answers but I have some unanswered concerns that I hope to get resolved in this thread. Also if this thread belongs in the Legal and Activism section, mods please move the thread as appropriate. Thanks
So here is the situation:
I found a Pistol on AR15.com that I would like to purchase. We (seller and myself) have agreed on a price but he is inquiring if my FFL will accept shipment from a non FFL. Meaning, he will send it directly to the FFL. First question is if anyone knows a FFL here that will accept that? [18 U.S.C. 1715, 922(a)(3), 922(a)(5) and 922 (a)(2)(A)] states that a non FFL can ship to a FFL but handguns are not "mailable" by USPS and that a common or contract carrier must be used. Is that UPS and Fedex?

Would it be easier to have it shipped to Oregon where I have a relative who can receive it as his and transfer it into my name when I get there next month then bring it back to Hawaii as out-of-state then register it? I can still purchase in Oregon as I have a Oregon driver's license.
Has anyone purchased a handgun from a forum or the like? How did you ensure you got the item after paying?
Sorry for all the questions, but I want to be squared away. Thank you for any info in advance!
