"The Distinguished Service Magnum Stainless" - This was a great find - this Model 681 is a more rare fixed-sight version of the classic 686. This particular Smith & Wesson was the carry gun of a police captain - which is to say that the only gun in the department shot less was the chiefs. I picked up this beauty with original box and papers - it had only been fired four times for annual qualification. Not any more. Great shooter!
