During his service with Colby, it was Colby's habit to always have a back-up piece in addition to what ever sidearm he carried. Most of the other troops considered that a little too gung-ho and gave Colby the nickname of ‘Two-Gun Bill.’ Back in the 1980’s, this fellow went to a unit reunion and saw Colby there. Talking to Colby, he asked him if he still carried two weapons . . .
Colby opened his jacket and showed his service piece - then rolled up his pants cuff and showed him his back-up. By that time, Colby was well into official retirement. FWIW, I think the ‘circumstances’ surrounding Colby's ‘accidental’ death were highly, highly suspect. This guy never did anything rashly or without an alternate plan. I suspect he was professionally murdered.
Fascinating story. So many things, we’ll never know.
