What is the minimum barrel length for a shotgun?

The minimum barrel length for a shotgun, according to federal regulations, is 18 inches. This standard ensures that shotguns are classified correctly and control their use in a manner that promotes safety. A shotgun with a barrel shorter than 18 inches would be classified as a "short-barreled shotgun," which is subject to more stringent regulations, including registration under the National Firearms Act. This requirement plays an important role in maintaining a framework for firearm regulation and ownership, balancing personal rights with public safety concerns. Understanding these specifications is crucial for those involved in training and certification under the Lethal Weapons Training Act (Act 235).
