California Firearm Safety Certificate Practice Test

The classification of firearms under California law includes handguns, rifles, shotguns, and certain air guns, making this option the correct choice. California's legal definition of a firearm is broad and encompasses various types of weapons. Handguns are typically categorized for their ability to be fired with one hand, while rifles and shotguns are often distinguished by their design and firing mechanism, which typically requires two hands or is meant for a shoulder-fired approach, respectively.

Additionally, certain air guns that operate at a specific velocity or energy level are also included within the classification. This inclusivity is crucial for ensuring that laws governing the safety, use, and sale of firearms cover a wide range of weaponry that could potentially be hazardous or regulated.

Regarding the other options, they are overly restrictive or misrepresent California's inclusive approach to firearm classification. The exclusion of handguns, rifles, and shotguns from the definitions would not accurately reflect the state's legal standards. Antique firearms are also a specific category but do not encompass the broader classification needed to understand what constitutes a firearm in the state.
