What defines a short barreled shotgun?

A short barreled shotgun is specifically defined by its barrel length, which is less than 18 inches. This definition is important because shotguns with shorter barrels are subject to specific regulations under federal and state law due to their classification as firearms that may be more easily concealed. The 18-inch threshold is critical in distinguishing between standard shotguns, which generally have longer barrels for improved handling and accuracy, and those considered short barreled, which may present different risks and considerations for law enforcement and public safety.

Other definitions, such as a shotgun with a barrel length of 16 inches or modifications involving detachable magazines, do not accurately capture the legal definition of a short barreled shotgun. Additionally, limiting this classification to shotguns designed for law enforcement does not align with the regulatory framework that governs firearms irrespective of their intended use.
