Saw a couple of 686 Customs Service, but they were six shot. When I saw a 3" seven shot I bought it. I have three other seven shots, and like them. The problem with my 3" is that the satin finish is gone on the face of the cylinder. The gun was only fired 150 rounds by the previous owner, but he cleaned the cylinder face with a lead away cloth. It removed the satin finish on the cylinder face! I contacted S&W. They want $59.00 to refinish the cylinder. My other option is to polish the rest of the gun and remove the satin finish, which I might do.
