I hope the experts chime in but I would say, "no." The older Smith and Wessons were denominated by names such as Military & Police, 357 Magnum, Highway Patrolman, 44 Magnum; Later, the same guns became the Model 10, 27, 28, and 29, respectively. The K38 Masterpiece was the old name for what became the Model 14. Same same, imho.
