The Benelli M2 Field is a 20-gauge semi-automatic shotgun with a 24-inch barrel, 3+1 capacity, and a matte black finish. It runs on Benelli's inertia-driven system, which is mechanically simple and known for reliable cycling across a wide range of loads.

Features 

 
The ComforTech stock uses a gel recoil pad and a vented comb to cut felt recoil noticeably compared to a standard synthetic stock. Length of pull is 14-3/8 inches. The Crio choke system is compatible with Improved Cylinder, Modified, and Full chokes so you can tune the pattern to your target. A red-bar front sight comes standard. 
 
At 5.8 lbs., the M2 Field is light for a semi-auto shotgun, which matters when you're carrying it through the field all day. 20 gauge recoil is already lighter than 12 gauge, and the ComforTech stock reduces it further, which is why this gun is popular with smaller-framed shooters. The inertia action does prefer standard-pressure loads over light target loads.

The Benelli M2 Field in 20 gauge gets consistently good marks across hunting and sport shooting communities. The inertia system's reliability comes up often — it cycles without much fuss and the simple mechanism doesn't require frequent maintenance. Owners hunting upland game specifically appreciate the light weight for long days in the field.

The ComforTech stock is mentioned frequently as a genuine feature rather than marketing. Shooters who've compared it against a standard synthetic stock report a real difference in felt recoil, which matters for a gun that may see a lot of rounds during a clay session or dove season.

The price is the main criticism. The M2 sits at a premium compared to alternatives from Mossberg or Browning, and some buyers debate whether the Benelli name commands too much of a markup. Others argue the build quality and long-term reliability justify it. Aftermarket customization options are somewhat limited relative to more mainstream platforms, though Benelli's own accessory ecosystem covers the basics.
