Hello
The Model 15 is the combat issue revolver associated closely with the Target Masterpiece model 14. It has a 4" barrel unlike the Model 14's 6" Barrel, and wears a Baughman front sight rather than the Patridge sight seen on the model 14. They were widely used by Law enforcment, along with many supplied for the Millitary and used as side arms and favored for their shorter 4" barrels and quick draw front sight which allowed a faster draw, over the Longer barreld model 14's. They came either Blued or Nickel and were chambered in the .38 Special cartridge. They were as accurate as thir Longer barreled cousin the model 14 and Possibly the most accurate .38 K-Frame revolver S&W ever made. Most that have had or still have one recognize their glassy smooth actions and inherint accuracy and favor this model for serious target shooting, or as a side arm adding protection of daily carry.
