Oh... If you do need to go to UPS to drop it off, you might want to take the time to check if ANY UPS Store (store front) will accept it, or if you need to go to a 'Depot' Office.
When Springfield was doing their XD-S Recall, at first, MANY of the 'Stores' wouldn't accept Firearms. They ended up needing a Special letter from Corporate saying it was okay "In This Instance". Same goes for drivers picking up the recalled XD-S. They needed special dispensation from above.
While I believe Springfield used FedEx, instead of UPS, being firearm/ammo related, you MAY encounter the same resistance, if you just go to one of the Stores. This may also be why nobody's coming to pick it up.
Hopefully this won't be an issue though.
