Silk road had a policy against selling items with intent to harm like guns. While occasionally some weapon listings would slip through, they would be taken down. The focus was drugs (and a lot of legal media). There were plenty of other black market sites on the dark web that sold everything, but that's not what the silk road in particular was about.
