Benelli 20 Gauge Semi-Automatic Shotguns

Benelli shotguns are renowned for their premium construction, ergonomic design, and the innovative technology they are built on. While their bread-and-butter is semi-auto shotguns that use their proprietary Inertia Driven® system, they also make pump-action and over-under shotguns.

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.
