"More powerful and than the SPAS-12. Gets the job done even better."
-Logan commenting on the Benelli M4
The Benelli M4 is a modern day shotgun currently deployed by the US Military and multiple other nations, although to date it has only been used in the war in Iraq and Afghanistan. Although it uses the same cartridge as the SPAS-12, it possesses higher muzzle velocity increasing damage and a shorter diameter barrel, resulting in less spread and more accuracy at longer ranges.
