When I shipped my Sig to the factory for the voluntary P320 trigger upgrade, I checked on the shipping rules.
If shipping a handgun, you must use UPS, FedEx, or other commercial shipper if not going through an FFL. If you use an FFL, they are allowed to use USPS to ship handguns.
If the handgun is going in for repairs and will be returned, you are not doing a transfer. Therefore, no FFL is needed in the process at all. If the factory or gunsmith doing the repairs has an FFL (is licensed), you're legally allowed to ship to them directly.
I used FedEx. Can't use the FedEx drop locations like Kinkos or Mailboxes, Etc. Had to drive to the main FedEx office on Lagoon Drive.
Anyway, the process was just as it's outlined on the ATF website and numerous gun related websites.
The one exception to this is in the return shipping. If the gun can't be repaired, but is instead replaced, then that constitutes a transfer. You'll need to have a local FFL take receipt, then do the whole Permit process to pick it up. Different serial number = new transfer.
