What is a Heavy Duck Gun? I have three 12 gauge model 12s made in the late '40s-early '50s. Two have plain barrels and full chokes. The other one has a 3" chamber, full choke, and a factory solid rib. I always considered all three to be "field guns", as opposed to skeet or trap guns. Someone recently told me the 3" chambered gun was a Heavy Duck gun. Is there a standardized definition of a Heavy Duck gun? What is the difference, if any, between a 3" field gun and a Heavy Duck gun?
