Gunsmithing

If you have access to a gunsmith's kit, you can create and restore firearms, craft bullets, and mix black powder for all types of firearms. You do not need to make a Craft check to create firearms and ammunition or to restore firearms.

If you are a gunslinger, this feat grants the following additional benefit. You can use this feat to repair and restore your initial, battered weapon. It costs 300 gp and 1 day of work to upgrade it to a masterwork firearm of its type.
