Which firearm length is classified as a handgun?

A firearm is classified as a handgun based on its overall length and design, which typically includes a barrel length that is relatively short compared to other firearms. The definition of a handgun generally refers to a firearm that is designed to be held and fired with one hand, and typically has a shorter barrel length which allows for a compact size.

In many jurisdictions, the legal classification of a handgun often stipulates that a firearm must have an overall length of less than 15 inches to be considered a handgun. This classification recognizes the smaller, more portable nature of handguns compared to longer firearms such as rifles and shotguns.

The answer indicating “less than 15 inches” accurately aligns with these legal standards, illustrating why this answer is correct. Other lengths provided overstep this limit, thus not conforming to the commonly accepted definition of a handgun.
