Two year Army vet. My MOS 15E, Pershing Missile Crewman, but I worked as an S-2 clerk in a Pershing Battalion HQ. My desk came with a loaded M1911. There didn’t seem to be any arms room accountability, it was just there. S-2 is intelligence and security, and often my duties required being armed with an M1911 or .38 “on the Strasse”, i.e., in off base settings in Germany. On these occasions, I would draw a pistol from the arms room. Turns out during an AGI they realized that I had been drawing pistols from the arms room regularly, without ever receiving any pistol training, except with a Fanner 50 as a boy. They took a bunch of us to the pistol range where in about 15 minutes we all qualified with pistol. My Fanner 50 training paid off. We didn’t use swivel holsters in the Army.
