Description
The Benelli M2 20 Gauge with a 28-inch barrel and Max-7 finish represents a considered choice for the waterfowl hunter who values reduced recoil without sacrificing reach. For the U.S. sportsman navigating tight timber, flooded timber, or open marsh, this 20-gauge platform offers a lighter carry weight and faster swing compared to its 12-gauge counterparts, while still delivering the pattern density needed for ethical shots on ducks and geese. Whether you are a seasoned hunter looking to cut down on fatigue during a long season or a newer shooter seeking a manageable semi-automatic action, the M2 20 Gauge provides a reliable tool for the field.
What This Product Is and Who It Is For
The Benelli M2 is an inertia-driven semi-automatic shotgun chambered in 20 gauge. This specific model features a 28-inch barrel with the Max-7 finish, a durable, non-glare coating designed to withstand the corrosive environment of coastal marshes and heavy rainfall. This shotgun is intended for the waterfowl hunter who values dependability over complexity. It is also a strong fit for upland bird hunters who appreciate the lighter weight of a 20-gauge gun for walking miles of fields and brush. While not a primary choice for home defense or concealed carry due to its barrel length and intended use, the M2 platform is well-regarded for 3-gun competition in the 20-gauge divisions, as well as for recreational clay shooting. Collectors will note the Max-7 finish as a distinct, hard-wearing option that differs from standard blued or synthetic finishes.

Feature Deep-Dive
The Benelli M2’s inertia-driven system is its defining characteristic. Unlike gas-operated shotguns, the M2 uses the recoil energy from the fired shell to cycle the action. This results in fewer moving parts, less fouling buildup, and a cleaner running gun in harsh conditions. For the waterfowl hunter, this means you can spend more time focusing on the birds and less time cleaning your firearm after a day in the marsh. The system also contributes to the gun’s light weight, as there is no heavy gas piston or complex cylinder assembly under the forend.
The 28-inch barrel paired with the Crio choke system provides a balance between swing speed and pattern control. The Crio process involves cryogenically treating the barrel and choke tubes, which relieves internal stresses and produces a more consistent bore diameter. This translates to tighter, more uniform shot patterns at typical waterfowl ranges. The ventilated rib helps dissipate heat and provides a clear sight plane, while the single red fiber-optic front bead allows for quick target acquisition in low-light conditions—common during early morning duck hunts.
The Max-7 finish is not simply a cosmetic upgrade. It is a multi-layer coating that offers significant resistance to saltwater, mud, and abrasion. This is particularly relevant for hunters who operate in coastal estuaries or flooded agricultural fields where moisture and debris are constant. The matte finish also reduces glare, which can alert wary waterfowl to your position. The synthetic stock is designed to handle temperature extremes without warping or cracking, and the shim system allows you to adjust drop and cast to fit your shooting stance and eye dominance.
Recoil management is a key consideration for any shooter, and the M2 20 Gauge benefits from the inherent lower recoil of the 20-gauge cartridge combined with Benelli’s Comfort Tech stock system. The stock features a gel recoil pad and chevron-shaped buffer inserts that absorb and redirect recoil energy away from the shooter’s shoulder. This makes the M2 comfortable to shoot for extended sessions, whether you are running through a box of shells at the pattern board or working through a limit of geese. The reduced felt recoil also aids in faster follow-up shots, as the shooter can stay on target more easily.
Maintenance is straightforward. Field stripping the M2 requires no tools beyond a punch or a shell rim to remove the trigger group. The bolt and inertia spring are easily accessible for cleaning and lubrication. Because the action does not vent gas into the receiver, carbon buildup is minimized, and the internals remain cleaner for longer. This is a practical advantage for hunters who may not have time for a full detail strip after every outing.
The 20-gauge chambering offers a specific advantage for the waterfowl hunter: lighter ammunition. A box of 20-gauge 3-inch shells weighs noticeably less than a comparable box of 12-gauge loads. When carrying several boxes into a marsh, the weight savings add up. Additionally, the 20-gauge M2 handles well for smaller-framed shooters or those who prefer a trimmer gun. The overall length of 49.5 inches and sub-6-pound weight make it a nimble choice for shooting from a layout blind or a pirogue.
Ideal Use Cases
This Benelli M2 is purpose-built for waterfowl hunting. The 28-inch barrel provides sufficient velocity and pattern density for pass-shooting ducks and geese, while the Max-7 finish stands up to wet, muddy conditions. It is also well-suited for upland hunting, particularly for pheasants, chukar, and quail, where the light weight and fast handling are assets. For the clay target shooter, the M2 can serve as a reliable field gun for sporting clays or skeet, though dedicated target models offer longer barrels and higher ribs. The M2 is not recommended for home defense or concealed carry due to its barrel length and intended field role, but it can be used for 3-gun competition in divisions that restrict gauge size.
Compatibility Notes
- Ammunition: The M2 cycles reliably with 2.75-inch and 3-inch 20-gauge shells. Light target loads (1 oz. or less) may require a break-in period of 100-200 rounds of high-velocity ammunition for optimal cycling. Heavier field loads function without issue from the first shot.
- Chokes: Uses the Benelli/Beretta Mobil choke thread pattern (Crio series). Standard aftermarket chokes from Briley, Carlson’s, and Patternmaster are compatible.
- Holsters/Slings: Standard 1-inch sling swivels are pre-installed. A sling is recommended for field carry. No holster is applicable for this firearm.
- Magazines: The magazine tube is fixed. Extended magazine tubes are available from aftermarket suppliers for non-migratory bird use, but must comply with state and federal regulations for waterfowl hunting.
- Accessories: Benelli offers a range of shims, recoil pads, and stock spacers. The receiver is drilled and tapped for scope mounts if a red dot or scope is desired for turkey hunting or slug use.
