Detailed Features 

The inertia-driven action cycles reliably across a variety of load weights without requiring gas system adjustments. The ComforTech stock is designed to reduce felt recoil, useful for extended sessions, particularly in 20 gauge where some lighter loads can produce a sharper impulse than expected. 
 
Three Crio chokes (IC, M, F) are included, covering the range from open patterns for close birds to tighter patterns for longer shots. The length of pull is adjustable at 14-3/8 inches, making it easier to fit different shooters. At 6 lbs., the gun is light enough to carry all day without fatigue. 
 

Usage 

The M2 Field in 20 gauge fits upland hunting, small game, and clay target shooting well. Hunters who want to keep pack weight down while maintaining semi-automatic cycling speed will find the 6-lb. weight a genuine advantage.

The Benelli M2 Field Gen 3 in 20 gauge draws mostly positive feedback from owners, with the lightweight build and reliable semi-automatic action coming up most often.

Handling is a consistent positive. At 6 lbs., the gun is easy to carry on long hunts, and owners who use it for bird hunting and upland game specifically mention the weight as a reason they chose it. The semi-automatic operation is described as smooth and reliable, and most owners feel confident cycling a range of loads through it.

Versatility comes up too. Owners use it for bird hunting, clay shooting, and occasionally mention home defense. The black anodized finish draws favorable comments on durability.

Price is the main critique. The M2 Field sits at the higher end of the 20-gauge semi-auto market, and some buyers flag this when comparing alternatives. A minority of owners note that with lighter loads the recoil feels snappier than expected, which is a 20-gauge characteristic more than a gun flaw. Overall the M2 Field gets recommended as a dependable, well-built field shotgun for those who want the inertia system's reliability in a lightweight 20-gauge package.
