Thanks Bill.
Here is a couple pictures of my "security holster" with "string.
I didn't have a seal, and gave the string an "extra" wrap around the grip.
I can envision a tag on the string also, with info and serial number of the pistol, to make recording data for transfer from stock to a smaller issuing entity easier, and then finally to the ultimate user.
Applying the "seal" and tag to an inspected, test fired, and cleaned pistol, would have been way more efficient than having to look at the pistol for the serial number each time it was "moved"
JMHO.
