The father of one of my friends, was a radio station operator, and upon his return to the states for discharge at San Francisco, he had a carbine and a .45. They asked him to pay for the carbine (which he was issued, per his rating) but not for the .45 (which had been given to him at his duty station). So he did, both.
There was more than a little variation on the practice, especially depending on who was on duty, and the time of day. Clearance personel at 2am, trying to process a shipload of troops tend to cut a few corners to get finished so they can all get some sleep.
