The Mossberg 500 and its sister weapons are pump action, hammerless repeating shotguns that all share the same actions and receivers. The Mossberg 590 shotgun is commonly used by the U.S. military, even though officially is switched to the Benelli M4 Super 90, due to its cheap cost, durability, and reliability. It's an effective weapon against zombies, as most shotguns are, due to the high stopping power of a 12 gauge shell. However, the rate of fire for a pump action may be slow for anyone not used to a pump action system. Also, the maximum of 8 shots limits its use, and it must be reloaded often. Compared to similar shotguns, the Mossberg is a great choice for close combat, and it can last a good amount of time.
The main difference between the 500 and its sister shotgun, the 590, is the way the barrel is held onto the magazine tube. On a 500, the magazine is closed at the end, and the barrel is held on with a bolt, which makes for easy barrel replacement. The 590 is open at the end of the magazine, the barrel fits onto the end of the tube and is held on by a nut, which makes the 590 much easier to clean. This means that if you're planning on using the shotgun for different purposes (slugs, etc.), you'd be better off with the 500, but if you're using it in heavy combat, then the 590 is your choice.
