Louisiana Gun Laws and Firearms Safety Practice Exam 2025 - Comprehensive Study Guide

In Louisiana, it is illegal to possess shotguns with a barrel length less than 18 inches. This restriction is in line with federal regulations under the National Firearms Act, which classifies shotguns with a barrel length less than 18 inches as short-barreled shotguns (SBS) and requires specific registration and licensing to possess them legally. This regulation aims to control the possession of more concealable firearms that could potentially be used for criminal activities.

The other options are not inherently illegal to possess in Louisiana. Semi-automatic rifles and handguns with a magazine capacity of over 10 rounds are not prohibited by state law, though there may be certain restrictions or additional regulations related to their use in certain situations. The correct answer, option B, distinguishes itself as the only choice representing a category of firearms that is explicitly illegal to possess without proper authorization in Louisiana.
