They designed the M2 with a 3-inch chamber. It can fire 2¾-inch magnum loads or 3-inch magnums without change. Its magazine can hold up to five rounds at a time and its barrel is replaceable from 20″, 24″ to 26″.

The design has a removable trigger group for easier cleaning. The design also includes an adjustable grip for mounting the shotgun to your body.

The Benelli M2 has a self-adjusting four-lug rotating bolt head. This feature guarantees smooth loading and ejection.

The firearm has an inertial control system. This system reduces recoil and ensures reliable cycling. It can function in extreme temperatures or dirty conditions. The balance point of the M2 is right in front of the pistol grip. This allows for quick target acquisition and quick follow-up shots.

The M2 is available in a variety of finishes including black, camo, gray and OD blue. Benelli released the Tactical version of the M2 in 2020. It features an 18.5-inch barrel and adjustable ghost ring sights. The sights help improve accuracy when targeting moving targets.

Main Differences Between Benelli M2 vs M4 Shotgun


When talking about price, the M2 beats its M4 counterpart Benelli as it is cheaper than the Benelli M4 series.

The price difference is vast as the price of the M2 shotgun is the lowest among the M series of Benelli, while the Benelli M4 shotgun is the most costly model.

Design And Ergonomics

The M2 is an inertia-driven gun, allowing it to operate cleaner than the gas-operated shotgun.

During testing, we noticed that the Benelli M2’s ComforTech feature makes it smoother and easier to fire than its Benelli M4 counterpart, which is heavy, fires softly, and chugs ammo.

The Winner: The M2 Benelli.

Weight And Size

The stocks of both shotguns have the same weight, while the barrels are also similar.

But the M2, as an inertia model, is lighter than Benelli M4 when comparing similar models.

As the M2 is lighter, its portability will be better, which is very important in many situations.

The Winner: The M2.


There is no denying that the M4 Benelli shotgun is reliable as it operates on a dual short-stroke gas piston system (which may be bomb-proof).

Meanwhile, the M2 Benelli runs on the tested and tried Inertia-Driven system, which is also quite reliable.

Both models work one hundred percent accurately with slugs, so the result in this category is one draw.

The Winner: Draw.
