The Benelli M2 is widely regarded as one of the more dependable semi-auto shotguns for upland and waterfowl hunting. Owners consistently mention that the Inertia Driven action keeps running with minimal cleaning, even after full days afield in wet or dusty conditions. A common complaint is that the gun can feel sensitive to very light target loads until it is broken in.

In the field, the M2 Field is praised for pointing quickly and carrying well over long walks, since it tends to run lighter than gas-operated shotguns in the same gauge. The Progressive Comfort stock draws favorable comments from hunters who shoot heavier loads through the season, though a few find the factory recoil pad firmer than expected.

On value, the M2 sits in the middle of Benelli's lineup, and most owners consider it a fair trade for the reliability and resale value the brand carries. Newer shooters sometimes note the price is still a jump over comparable gas guns, but longtime Benelli owners tend to see it as worth paying for.
