An additional 352,315 Victory Model revolvers chambered in the well-known and popular .38 Special cartridge were used by United States forces during World War II. The Victory Model was a standard-issue sidearm for United States Navy and Marine Corps aircrews, and was also used by security guards at factories and defense installations throughout the United States during the war. Although the latter personnel could use conventional lead bullets, Remington Arms manufactured REM UMC 38 SPL headstamped cartridges loaded with a full metal jacket bullet for military use in overseas combat zones. Tracer ammunition was manufactured for signaling purposes.
