The S&W Model 10 military revolvers produced from 1942 to 1944 had serial numbers with a “V” prefix, and were known as the Smith & Wesson Victory Model. It is noteworthy that early Victory Models did not always have the V prefix. During World War II over 570,000 of these pistols were supplied to the United Kingdom, Canada, Australia, New Zealand, and South Africa under the Lend-Lease program, chambered in the British .38/200 caliber already in use in the Enfield No 2 Mk I Revolver and the Webley Mk IV Revolver. Most Victory Models sent to Britain were fitted with 4-inch or 5-inch barrels, although a few early versions had 6-inch barrels.
The Victory Model was used by United States forces during World War II, being chambered in the well-known and popular .38 Special cartridge. 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.
