.357 Magnum, N-Frame. The Model 27 revolver was extremely popular among law enforcement officers. Many police agencies were interested in purchasing such a weapon — except for cost. In 1954, S&W produced a new model called at the time, "Highway Patrolman". It had all desirable performance features of deluxe Model 27, but lacked cosmetic features that drove up price. Finish matte blue; rib sandblasted instead of checkered or serrated; grips standard checkered walnut. Barrel lengths 4 and 6.5 in. On late models, 6.5-in. barrel reduced to 6 in., as on all S&Ws. Designation changed to Model 28 in 1957. S&W discontinued the Model 28 in 1986. Note: 3 engineering changes.
