I,just found this..... matt2109 maybe your UPS was not convinced your GF was 21 and if she knew it was a gun and he asked for ID she assumed LTC?
.. Adult Signature Required: UPS will obtain the adult recipient's signature and provide you with a printed copy. Adult recipients must be at least 21. You may also view the adult recipient's signature online
I know at least 4 CR deliveries to my home my wife was ID'd for age.
I get all my deliveries at work now and have had the same ups/fedex drivers for 10+years.
I think this is the most likely explanation. My GF, is hard of hearing, he may have id'd for age and she assumed LTC.....
