About 15 years ago, I was an IDPA competitor. In those days, I was shooting black stainless Sig 229’s of the 357Sig persuasion in competition. It was pretty common for me to send them to the Sig performance center to get work done. Because of employee theft, UPS had a requirement that all handguns had to be sent overnight and insured. This was way too expensive at more than $200 per handgun.
Now I didn’t think that I should be forced to pay more to UPS because UPS couldn’t keep their employees from stealing. The law said that those who shipped firearms via common carrier had to notify the carrier of the contents of the shipment. So I would always list the contents as “Sig Sauer Model 229” and ship it standard and insured. It cost less than $30 and still complied with the law.
