My insurance company- Insure Collect- requires USPS for guns over $12,000. Fed X is the second teir with UPS comming in last as to coverage from the insurance carrier.
As with any common carrier i have found that proper packaging is the most important aspect. Any of the carriers can calim"improper packaging" and leave you at risk.
I know a good many use the plastic molded cases for shipment. I have chosen heavy double box corregated and have had zero damage or loss using all three carriers.
With UPS and Fed X you do not declare contents.
