What weapons were issued to pilots, whether it be American, Japanese, or German?

[special ed]

Although not actually involving pilots hand guns, my late brother in law was in charge of the firearms property room of a large city and had to dispose of some firearms depending on circumstances. This meant crushing in a large hydraulic press. As he liked firearms, he would strip the parts and crush only the frame with the serial number. On occasion, Feds would want something crushed and it had to be observed. One day, he was rather quiet and I asked why. He said the Federal Reserve Bank sent over an M-16 and five old Winchester parkerized shotguns (WW1 era) in perfect shape, apparently unused that had to be completely crushed.
