Recently on another firearms forum there was a discussion about the Smith and Wesson Military and Police revolver, later designated as the Model 10. Okay, so far, so good. However, during the thread other S&W models were also referred to as Military and Police Models (M&P's), such as the Model 12, Model 14, Model 19, etc.. Two different uses of the term M&P -- one as the name of a specific model, and one as a category. Now, I have been shooting Smiths for most of my life, and I never heard the term S&W Military and Police used to describe anything but what was later called the Model 10. The Model 19 was the "Combat Magnum", the Model 14 the "K-38", the Model 15 the "Combat Masterpiece" etc. I never heard them called the M&P Model 19 or whatever. Have these decendents of the original Model 10 always been known by the Military and Police designation, and I just never noticed it, or has it been a more recent categorization?
