Here is one example, a group of pirate NPCs called "The Crew of the Albatross"
You will find two named NPCs, Maria Tres Pistolas and Gnarly Tom, as well as group statblocks for veteran pirates and novice pirates (level 0).
For the time being, they have no firearms. Perhaps soon Paizo will give us improved firearms rules. I may simply use firearms as listed in the Freeport setting, adding the "deadly" attribute with a die size increased by one step.
Comments? Suggestions?
