Regarding soldiers keeping their issued weapons, when my father-in-law was discharged after World War One, he bought his .45 1911 for $24 (it's right there on his discharge papers, which we still have). Later, as a postal inspector, he carried it as his personal sidearm. He was involved in several of the 1930s gangster chases, including Bonnie & Clyde's (but not the finish). Died in 1995 at almost 101, he and his wife now lie in Fort Rosecrans up on Point Loma, overlooking San Diego Bay. My wife insisted on selling that 1911, despite my entreaties. She got $250 for it. With its documentation and history, it would bring in thousands now. Or better yet, remain in the family in remembrance of a fine man.
Cordially, Jack
