About the K38 / Pre-Model 15

The K38 Masterpiece (later designated the Model 15 Combat Masterpiece) is one of the most celebrated K Frame revolvers ever produced. Pre-model revolvers predate the 1957–58 model number system; if your revolver has no model number stamped behind the yoke, contact us with the serial number and we'll confirm compatibility.
