PFS S8 says gunslingers can use craft（gunsmithing）,just like Alchemists and Investigators can use craft(alchemy),but I dont konw wheather this craft skill can make a gun by 1/3 cost or just can make bullets.
Rule says that alchemists can not sell their products,but I dont konw any rules say gunslingers also can not sell their guns producted by craft skill.
Can a gunslinger use craft skill to sell an unlimited amount of guns and get an unlimited amount of gold?
