L-Roy is right -ON!
The S&W Model 10 Military and Police .38 Special revolver is truly a classic. It was THE American police sidearm for several generations.
As for accuracy, it's built on the K or medium frame and is/was the basis for the K-38 Masterpiece (M14), Combat Masterpiece (M15), Combat Magnum (M19), .22 Masterpiece (M17), and all the stainless steel variations of the same guns. These K-frame guns dominated the PPC competition for generations, and right out of the box, many guns could give near one-hole accuracy when fired from a machine rest.
Years ago, I built several PPC competion revolvers, and showed the pistol machine rest target groups to the customers. Many were astounded that the stock 4" barrel could shoot groups nearly as well as the custom ribbed, target-sighted, thick-barreled piece they paid several hundreds of dollars for!
