Just pray your tool doesn't fall out because you will not collect insuranceExcellent last line report……….UPS is the safest shipment carrier……any long gun is legally shipped to yourself, handguns not sure about. If these guns are transferred to your ownership in HA, then transportation from/to yourself is legal.
When I have shipped guns in the past, I always used UPS, declared it a “ tool “, to not draw attention, to deter theft, & always insured the package for replacement value.
