Smith & Wesson K Frame Model K38 Pre-Model 15 Hammer Block – Old Style
Restore your K38 or Pre-Model 15's passive drop safety with this factory-original hammer block. The hammer block is a critical internal safety component that prevents the firing pin from contacting the primer unless the trigger is fully depressed — protecting against accidental discharge from drops or impacts. This old-style blue steel hammer block is the correct replacement for the K Frame Model K38 (Pre-Model 15) chambered in .38 Special.

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.
