Benelli 20 Gauge Semi-Automatic Shotguns For Sale

Benelli shotguns are renowned for their premium construction, ergonomic design, and the innovative technology they are built on.

Frequently Asked Questions

Is a Benelli 20-gauge enough for home defense?

While any gun is better than no gun, the 20-gauge isn't meant for home defense. It has less stopping power and penetration than a 12-gauge. While a 20-gauge is great for bird-hunting, we recommend 12-gauge shotguns for home defense.

What is Benelli's Inertia Driven® system?

The Inertia Driven® system was originally developed in 1967 by Bruno Civolani, and it's what set Benelli shotguns apart when they were first manufactured. Unlike gas-operated systems, there are fewer moving parts and no O-rings, gas cylinders, or other complicated parts. Its tried-and-true simplicity and reliability has cemented its position as the best shotgun operating system in the world.

Can you deliver my Benelli 20-gauge shotgun to my house?

No. All firearms can only be delivered to someone with an FFL. You'll need to have it sent to your local FFL dealer for pickup. For example, if you want to order a Benelli Montefeltro 20-gauge shotgun, you would confirm the dealer is willing to take the package, place your order, and then go pick it up from the dealer when it arrives.

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.
