A couple of months ago I sent a gun to Virginia via USPS for repair. Tracking showed that it got as far as Memphis and stopped there for a week, and I filed a lost report with USPS. After a few more days, on advice from the receiving gunsmith, I filed a report of a missing firearm with both my local police and an email to the ATF office. I never got a response from ATF but the gun arrived the next day and tracking showed that it started to move shortly after I emailed ATF. The timing may have been coincidence, but the gunsmith had told me of an identical experience with another gun lost by the post office.
