A gunsmith is a person who repairs, modifies, designs, or builds guns. This occupation differs from an armorer. A gunsmith does factory level repairs, renovation (such as applying metal finishes), and makes modifications and alterations for special uses. Gunsmiths may also apply carvings, engravings and other decorative features to an otherwise finished gun. The environment in which all this takes place often varies depending on the specific locality, with some gun stores featuring one or a handful of individuals while others resemble large scale specialty shops.
