What term refers to a person licensed to trade in firearms and ammunition?

The term that refers to a person licensed to trade in firearms and ammunition is "Dealer." A dealer is typically a business or individual authorized by law to buy and sell firearms and ammunition, often registered with federal and state authorities to ensure compliance with regulations surrounding firearm sales. This licensing process includes background checks and adherence to safety and legal standards.

In contrast, a collector is someone who gathers firearms for personal enjoyment or investment and may not necessarily be involved in selling them. An inspector is a professional who examines firearms, often ensuring they meet safety standards or legal definitions, rather than engaging in the trade. A handler typically refers to someone who is trained to handle firearms safely but does not imply a trade or licensing aspect related to buying and selling firearms.
