My uncle was a B-25 pilot in the 5th Air Force, Pacific Theater, during WWII. All crews had Colt 1911s and most of them also grabbed M1 Carbines and kept them on their planes.
He was shot down over China and spent six months running from the Japs and getting back to friendly lines. His whole crew made it back to American forces and returned to their group. He said that M1 Carbine saved his life several times.
My uncle got that carbine home and when he passed away my aunt gave it to me. It was made by IBM and will go to my son when I pass on.
