The Smith & Wesson 908 was derived from the earlier Smith & Wesson Model 39; that weapon was created in response to the United States military's request for a 9 mm pistol to replace the M1911. The Model 39 was not selected, but it underwent a few design changes and became the Model 908 ; the 908 was adopted by a number of police departments to upgrade their aging revolvers. The Smith & Wesson 908 functions best when regularly cleaned and lubricated.
