Editor’s Note: Johnny B says "Benelli’s M4 is what we would call a good Italian auto shotgun. It’s the best combat shotgun on the market and would do phenomenal in a home defense setup or tactical arena. This autoloader looks great, runs smooth, brings that cool factor we all like from our guns. Most importantly, you can trust your life to it." This 12-gauge shotgun is a fast-shooting, smooth semi-auto model. Featuring an 18.5-inch barrel, it measures 40 inches in total length with a weight of 7.8 pounds. It offers up a 14.75-inch length-of-pull. Drilled and tapped, you can throw an optic on it and rock and roll.
