Built as a DA/SA revolver with an exposed hammer, this Pre-27 is set up with an adjustable rear sight and a raised blade front sight mounted on the barrel rib. The sighting system and full-size frame layout reflect the classic configuration of early S&W .357 Magnum revolvers.
The barrel features a top rib, a full-length ejector-rod shroud, and a checkered/serrated top strap/top rib. These are defining external features on this example and contribute to its distinctive profile.
Markings include "SMITH & WESSON," "S.&W. .357 MAGNUM," and "MADE IN U.S.A. SPRINGFIELD, MASS." The Smith & Wesson circular trademark is present on the left sideplate, and a multi-line address block appears on the right side forward of the trigger guard.
This revolver is identified as serial number S159398 on the butt. With its 1956-1957 production era and Pre-Model 27 designation, it is presented as a collectible Smith & Wesson .357 Magnum from the period before formal model numbering.
