The Smith & Wesson Model 10, previously known as the Smith & Wesson .38 Hand Ejector Model of 1899, the Smith & Wesson Military & Police or the Smith & Wesson Victory Model, is a revolver of worldwide popularity. It was the successor to the Smith & Wesson .32 Hand Ejector Model of 1896 and was the first Smith & Wesson revolver to feature a cylinder release latch on the left side of the frame like the Colt M1889. In production since 1899, it is a six-shot double-action revolver with fixed sights. Over its long production run it has been available with barrel lengths of 2 in (51 mm), 3 in (76 mm), 4 in (100 mm), 5 in (130 mm), and 6 in (150 mm). Barrels of 2.5 inches (64 mm) are also known to have been made for special contracts. Some 6,000,000 of the type have been produced over the years, making it the most popular centerfire revolver of the 20th century.
Many of the Model 10 revolvers were captured and used by some of the police forces, such as the Austrian Police during the occupation after WWII and some captured from the allies used by the pro German Milice française during WWII.
The weapon is currently used by Armaguard, French cash couriers and banks, Disciplined Services of Hong Kong, Myanmar Police Force officers and other Burmese paramilitary units, Peruvian National Police and other police units.
Copies of Smith & Wesson Model 10 are produced in Israel by Israel Military Industries (IMI), in the name of Revolver IMI 9mm. The weapon is chambered in the 9x21 mm caliber instead of .38 Special, the original caliber chambered.
