While both shotguns have an 18.5-inch barrel, the Benelli M2 has a screw-in choke with an improved cylinder bore, while the M4 has a fixed cylinder bore choke.īoth shotguns have a durable construction with polymers on the stock and forend and offer high functionality and longevity. While some shotguns are made for close-quarter tactical combat, others can reach medium ranges, and that’s what the M4 does, in contrast to the M2’s power. If you want some short-range scopes or red dot sights, there’s a 5.25-inch Picatinny rail on the M4’s receiver.Īnother point for the Benelli M4. When it comes to optics, the M4 clearly dominates the field, as there’s no optic rail on the M2.īoth the M2 and the M4 have ghost rings, but Benelli M4 has a fully-adjustable LPA ghost right sight and a white dot front sight for fast target acquisition. There are even more configurations, but they’re not for civilian use.ĭespite being a lightweight model, the downside of the M2 is that it doesn’t have an accessory rail, so the possibility of aftermarket optics is taken away. The M4’s stock and grips configuration comes with either a tactical stock or a fixed stock with a pistol grip. The M2 boasts an adjustable ComforTech recoil-reducing pad that cushions the heavy inertia recoil. While both the M2 and M4 share the same weight and barrel length, the M2 weighs 6.7 pounds, as the inertia mechanism is lighter than the M4’s ARGO with an overall weight of 8.7 pounds, making it the heaviest Benelli product to date.īoth models have an oversized trigger guard, so you can use gloves. The M2 runs on the tried-and-true Benelli Inertia, but the M4’s is more powerful and reliable overall, so one point goes to the M4. Both the M2 and M4 cycle 2¾- inch and 3-inch shells excellently.

This unique system is very reliable, and it effortlessly handles 3-inch buckshot shells and field loads. The two gas-operated pistons work well with this system, and it’s self-cleaning as well, meaning it produces less gunk, so it’s easy to clean. The ARGO works with two highly reliable short-stroke gas pistons that give you an edge in fast follow-up shots along with a faster cycling rate, greatly lowered felt recoil, and lasting reliability.
