If you have the plastic box it came in, box that into the smallest cardboard box you can fit it in to. FedEx and UPS have them (you can't ship it via the US Post Office.) Tape it up good, attach the label and either take it to FedEx or a UPS HUB Office- not one of those UPS stores, they can't ship firearms. Don't write anything on the box, I was tempted to mark it "Firearm" but that's a bad idea. And yes, I put insurance on mine, it's really cheap. You also need to write up a good explanation of what is happening, and include any magazines you were using when it happend- no ammo, no spent shells. As mentioned before, we also write "Please be sure and notify me at (my email address) when you return-ship the pistol." Hopefully they will, so you'll know when it's coming.
