I just purchased one at a local gun store. The first Benellis available to the civilian market will be limited to 2500. These are a commerative version and have an american flag laser etched on the receiver and special serial numbers (1 - 2500).
The shotgun comes standard with a 4 shot mag tube, pistol grip stock, and ghost ring sights. There will be a 2 shot mag extension and a fixed stock available in the near future.
The shotgun supposedly has had fantastic reviews from the military. I am hopeful the recoil will be less than that of the M1 due to the new gas system.
