Good afternoon to you!! The filigree frame and barrel on the Colt King Cobra .357 Mag Revolver - 6 Rounds are hand engraved, not machine engraved. The King Cobra was known for its high-quality craftsmanship and attention to detail, and the filigree work on this specific model was done by skilled artisans, according to US Concealed Carry Association. Hope this helps. Have a good evening!!
