Pick up and hold new Wingmaster with Light Contour barrel (usually standard receiver with barrel chambered for 2&3/4, 3" and 3.5" cartriges) . You can't shoot 3.5" shells out of that setup nor would anyone want to but that is besides the point. The handling is superior to new Ithaca 37 and leaves PBS in the dust. The US military doesn't really know anything about shotguns. They picked 590A1 because that is probably the only one submitted for testing. The people at Remington weren't stupid enough to compete with Mossberg by trying to submit lower priced product.
I picked up Model 12 16ga and took it over next to Wingmaster to compare both. Remarkably the 12ga Wingmaster Light Contour came very, very close to the Winchester in handling department. All that and one gets 3" capability, vr plus choke tubes.
