The primary responsibility of a gunsmith is to ensure that guns work and function safely. Gunsmiths accomplish this by always properly observing and demonstrating firearm safety in their handling procedures: both in their own actions and in the actions of their customers and the people around them. They accomplish that task secondly by inspecting guns to ensure safe mechanical operation. Gunsmiths use their in-depth knowledge of guns to guide inspections: either repairing deficiencies or notifying customers of unsafe conditions and taking steps to prevent catastrophic failures.
Some of the conditions a gunsmith looks for when inspecting a firearm brought to them for repairs are improper assembly, missing parts, cracks, bore obstruction, improper headspace, improper timing, safety malfunctions, worn sear edges, and deformed firing pin tips, among other problems.
