Hunters have used shotguns for centuries. It was not until World War I that the military decided to introduce them into combat. While their range is limited, their effectiveness in trench warfare as they spread shots and hit moving targets at short distances was crucial. Many of today’s top shotguns are made in America by gunsmiths like Winchester, Remington, and Mossberg.
Shotguns are specialized weapons that are mainly used at short range. Instead of a single bullet, these firearms typically fire a burst of small pellets called “shot.” When the gun is fired, the pellets spread wide, increasing the chance of hitting a target at a close distance without the need for precise accuracy. The U.S. military utilizes shotguns for combat in close quarters since you don’t need to have perfect aim. In addition, some shotguns fire “slugs” — single, heavy metal projectiles. When fired, slugs can fly further and with more power than pellets. This extra power can be used to breach obstacles like hinges and doors, allowing soldiers to enter into secured locations quickly.
To identify every major American-made military shotgun since WWI, 24/7 Wall St. reviewed a catalog of shotguns from Military Factory, an online database of arms, vehicles, and aircraft used by militaries worldwide. We ordered the shotguns chronologically and included supplemental information regarding the type of gun and the year it entered service, as well as the manufacturer, caliber, and feed.
Why We’re Writing About American-Made Military Shotguns
For over a century, military shotguns have been a key tool for American soldiers, helping them to breach doors, clear trenches, and maintain an upper hand in close-quarters combat. Examining the shotguns used by the U.S. military can provide insights into the complex relationships between government spending, major defense contractors, and global conflict. The evolution of American-made shotguns, how they are adapted for specific roles, and which companies manufacture them also sheds light on technological advancements, budgeting priorities, and the constantly changing landscape of warfare.
