A firearms designer is a professional who specializes in creating and developing firearms, including handguns, rifles, and shotguns. They work on various aspects of firearm design, such as functionality, safety, and ergonomics. Their role often involves using computer-aided design (CAD) software to create detailed models and prototypes, which are then tested for performance and reliability. These designers must have a strong understanding of engineering principles, materials science, and ballistics. They often collaborate with other professionals, including engineers, manufacturers, and military personnel, to ensure that their designs meet specific requirements and regulations.
