9 mm is a European caliber. It is approximately equivalent to a 38 or 357 magnum. The 9 mm refers to the diameter of the barrel. It has nothing to do with the way the pistol is made. It can be a revolver and used like any other revolver or it can come as an automatic with a clip in the handle. The Germans used it in World War 2 just like the English and Americans used the 38. For a while police departments used it. However, police departments have mainly gone over to a 45 caliber automatic.
