Smith & Wesson K Frame Model 15-2 Thumb Piece & Nut — Blue Steel, Old Style, Used OEM Part

This is a used factory-original thumb piece and nut for the Smith & Wesson K Frame Model 15-2 Combat Masterpiece chambered in .38 Special. The thumb piece (cylinder release latch) and its retaining nut allow the cylinder to swing out for loading and unloading — a worn or damaged thumb piece causes cylinder release failures. Features the blued steel finish of the old style variant.
