problem with my p226 mk25

[whynot]

Call FedEx and ask then?

Normally FedEx won't print a label until after it's paid for, maybe this is something I have not seen...

shipping/insurance was paid for by sig! note that you have to take the handgun to a FEDEX hub to send it out, it can't be just any FEDEX, also make sure you ask the front desk on the procedure of bringing a handgun into fedex .

No amount of lube, grease or oil will do a darn thing when a steel burr digs into soft aluminum.....

My P228 had the same issue, after 100rds had a nice dig in the frame ~ Knocked down the burr & nothing has changed/ got worse. This was a NIB "used" pistol at a great price so I couldn't complain, if new I'd feel different.

This. Lube won't remove burrs for you, and thus it won't prevent damage or wear caused by them.
