Description
The Benelli M2 Field Synthetic 20GA with a 24-inch rifled slug barrel is a capable semi-automatic shotgun designed for hunters who demand reliable performance in the field and on the range. For U.S. shooters navigating dense cover or open agricultural land, this platform offers a lighter recoil profile without sacrificing the terminal performance needed for deer, hogs, or turkey. Whether you’re a seasoned sportsman or a newer shooter looking for a versatile shotgun, the M2 combines Benelli’s inertia-driven system with a synthetic stock that stands up to wet weather and rough handling.
What This Product Is and Who It Is For
The Benelli M2 Field Synthetic (model 11184) is a 20-gauge semi-automatic shotgun with a 24-inch rifled slug barrel and a black synthetic stock. It is built for hunters who need a dedicated slug gun for deer or other medium game in states that restrict rifle calibers, as well as for target shooters who prefer the reduced recoil of the 20-gauge. This shotgun is not designed for home defense in the traditional sense—its rifled barrel and slug-only capability make it a specialized tool for precision shooting at moderate ranges. It is also suitable for collectors who appreciate Benelli’s engineering heritage, but its primary audience is the practical hunter and range user.

Feature Deep-Dive
The Benelli M2’s inertia-driven operating system is the core of its reliability. Unlike gas-operated shotguns, the M2 uses the recoil energy from each shot to cycle the action, which means it functions without the fouling and maintenance demands of gas ports. This system allows the shotgun to run cleanly across a wide range of ammunition, from light target loads to heavy magnum slugs. For U.S. hunters who spend long days in wet or dusty conditions—such as swampy timber or dry agricultural fields—the lack of gas system debris reduces the likelihood of malfunctions. The inertia system also contributes to the M2’s relatively light weight, which is a practical advantage when carrying the shotgun over uneven terrain.
The 24-inch rifled slug barrel is a deliberate choice for accuracy with sabot slugs. The rifling imparts spin to the projectile, stabilizing it for consistent groups at ranges out to 100 yards or more, depending on the shooter’s skill and ammunition selection. The barrel’s length strikes a balance between maneuverability in brush and sufficient sight radius for precise aiming. The fixed cylinder bore ensures that only slugs—never shot loads—should be used, which eliminates the guesswork about choke selection. The barrel is also equipped with a ventilated rib, which helps reduce mirage on warm days and provides a flat reference plane for the adjustable rear sight.
The synthetic stock and forend are made from a reinforced polymer that resists moisture, temperature extremes, and impact. The black finish is non-reflective, which is useful for hunting scenarios where glare could alert game. The stock features a soft rubber recoil pad that reduces felt recoil, making the 20-gauge even more manageable for shooters who are sensitive to kick. The forend has a textured grip area, providing positive control even with wet or gloved hands. The overall ergonomics of the M2 are designed for fast shouldering and natural pointing, which is beneficial when tracking moving targets in the field.
The adjustable rear sight and fixed front sight are set up for slug shooting. The rear sight can be drifted for windage and adjusted for elevation, allowing the shooter to zero the shotgun for a specific slug load. This is a practical feature for hunters who want to maximize accuracy at known distances. The fiber-optic front sight is easy to acquire in low-light conditions, such as early morning or late afternoon hunts. The receiver is drilled and tapped for scope mounts, giving the option to add a red dot or low-power scope for shooters who prefer optics over iron sights.
The M2’s magazine tube holds three 2.75-inch shells, with the capacity to chamber a fourth round. The magazine is easily loaded through the bottom port, and the bolt release button is positioned for quick operation. The bolt handle and safety are oversized for gloved use, a detail that matters when hunting in cold weather. The shotgun also features a cross-bolt safety that is reversible for left-handed shooters. The overall build quality is consistent with Benelli’s Italian manufacturing standards, with tight tolerances and smooth action cycling that improves with use.
Weight distribution is another consideration. At just over 6 pounds, the M2 carries light but balances well due to the barrel’s length. This makes it suitable for hunters who walk long distances, such as still-hunting through public land or stalking in agricultural zones. The light weight does not compromise durability—the synthetic stock and aluminum receiver are proven to withstand years of field use. For shooters who want a dedicated slug gun that handles like a field shotgun, the M2 Field Synthetic offers a practical solution without the bulk of heavy competition models.
Ideal Use Cases
Hunting: This shotgun is primarily designed for deer hunting with slugs in states that restrict rifle calibers. It is also effective for hogs, black bear, or other medium game where a 20-gauge slug provides sufficient energy. The rifled barrel and adjustable sights allow for precise shot placement at typical hunting ranges of 50 to 100 yards. The 20-gauge recoil is lighter than 12-gauge, making it a good choice for younger or smaller-framed hunters.
Target Shooting: The M2 can be used for slug-specific target practice or for recreational plinking at steel or paper targets. The semi-automatic action reduces felt recoil compared to pump-action shotguns, allowing for longer sessions without fatigue. The adjustable sights help shooters dial in their zero for consistent accuracy.
Range Use: For shooters who frequent ranges that allow slug use, the M2 is a reliable tool for honing marksmanship. The inertia system cycles cleanly, and the light weight makes it easy to handle during drills. It is not intended for clay sports or bird hunting, as it will not accept shot loads.
Compatibility Notes
Ammunition: This shotgun is designed for 20-gauge sabot slugs and rifled slugs. Use only 2.75-inch or 3-inch shells. Do not use steel shot, birdshot, or buckshot—the rifled barrel will not pattern these loads effectively, and using shot can damage the barrel or cause unsafe pressure. Recommended brands include Federal Premium, Hornady, Remington, and Winchester sabot slugs.
Holsters and Slings: The M2 is not designed for concealed carry. For field carry, use a padded sling with quick-detach swivels (the stock and forend have sling studs). No holster is applicable.
Magazines and Accessories: The magazine tube is fixed and non-removable. Aftermarket extended magazines are not available for this model. The receiver is drilled and tapped for Benelli-specific scope mounts (see Benelli’s accessory guide). The stock accepts standard Benelli recoil pad replacements. The barrel is not interchangeable with other M2 models—this is a dedicated slug barrel.
