The most-produced handgun of the 20th century was a revolver

In short: While semi-automatic pistols eventually dominated the modern landscape, the Smith & Wesson Model 10 reigned supreme for nearly a century. From frontline soldiers to police officers and civilian shooters, this .38 Special powerhouse became an enduring icon of reliability, reaching a production milestone of over six million units.

The lineage of the Model 10 began in 1899 as the Smith & Wesson Military & Police. It was born from military necessity; when reports surfaced that the standard .38 Long Colt cartridge was ineffective in the Philippines, S&W introduced a more powerful .38 S&W Special. This new round featured a heavier 158-grain bullet and an increased powder charge of 21 grains. By 1902, significant internal modifications were made to simplify the lockwork and add a locking underlug to the barrel, creating a robust platform that would serve as the industry standard for decades.

During World War II, the revolver evolved into the 'Victory Model.' These were produced in high volumes for various international allies through the Lend-Lease program. While many were chambered for British .38/200 ammunition, others were chambered in .38 Special for U.S. forces. The Victory Model was particularly favored by Navy and Marine Corps aircrews because it was easier to carry in cramped cockpits than heavier pistols like the M1911. Notably, quality control issues during early production led to a 1945 design change that added an improved hammer block after a sailor was killed when a loaded revolver accidentally discharged on a steel deck.

The Model 10's cultural and practical reach was immense. It served as the standard police sidearm for 70 years in many regions and remained in active service with various U.S. military branches, including the Coast Guard, well into the 1990s. Even as late as 1991, it was used by Air National Guard tanker crews during Operation Desert Storm. Its transition out of primary service only began in earnest between 1990 and 2010, though its legacy persists; for instance, the Hong Kong Police only recently announced a move away from the model in 2024 due to manufacturing changes and parts availability.
