Factory tested in 1988. Per the "Standard Catalog of Smith & Wesson" 3rd Edition this is a transitional model "6450" (product code 103710) that retains the old model marking of "645". Consignor research states that this is "one of 300" released for commercial sale. With matching factory box, one extra magazine, and the factory test target.

Very good overall with minimal handling marks and minimal spotting. Mechanically excellent.
