The Military & Police became the model 10 in 1957. This is the classic S&W revolver and was the bread & butter gun for the company for decades. Now the tastes of gun consumers has shifted to fancy, hi-cap, tacticool self-loaders but the Model 10 got the job done for over 100 years and still continues to do so. My mother keeps a 5" 10-7 loaded with lead SWC HP +Ps in her nightstand. I have a 2" M64 in my own nightstand which is nothing more than the Model 10 in stainless.
