This .22 lr revolver is the stainless steel version of the Model 17, but unlike some of its blue brothers each 617 has a full Under Lug barrel.
The 617 model comes in the same barrel lengths as the Model 17 and can be found with either six or ten shot cylinders.
Built on Smith & Wesson’s medium-sized K-frame, the 617 is a great pistol for target shooting.
The model 17 has been around since 1947, but the blued versions were discontinued in 1998.
The 6 in 617 designates a stainless finish, which is still in production to this day.
