Tactical, Powerful, and Reliable

There are a few things that set semi-automatic shotguns apart from our other shotguns for sale. While pump-action shotguns are designed to be dead simple to operate and maintain, they require a manual pull to rack a shell or slug, slowing you down. Many over-under and side-by-side shotguns have a recoil-operated system or a selector switch that automatically prepares the second barrel for a fast follow-up shot, but these typically only hold two shots.

Semi-auto shotguns are simpler to operate than pump-action shotguns and have more rounds than side-by-side and over-under shotguns. They're also just as reliable. Experience one for yourself today with a shotgun from Sportsman's Outdoor Superstore.

Frequently Asked Questions

What are semi-automatic shotguns good for?

These shotguns are great for any application that requires the fastest possible follow-up shots. For example, some hunters use a semi-automatic over a pump-action for hunting waterfowl to get more shots off before the birds fly away. They're also popular for multigun courses, where the time it takes you to finish the course is as important as your accuracy.

Are semi-auto shotguns good for home defense?

Yes, semi-autos are great home defense weapons. Militaries and law enforcement agencies around the world use semi-automatic and fully automatic shotguns. If they can rely on these beefy weapons to protect themselves, so can you.

Can you ship a semi-automatic shotgun to my home?

Unfortunately, when you order guns online, you can't simply ship them to a residential address. Firearms must be signed for by someone with a Federal Firearms License (FFL). After you've gotten permission to send the gun to your local FFL dealer and ordered your shotgun, you can pick it up directly from them.
