Whats your favorite Weapon in COD?

my personal favorite gun goes wayyyyy back in COD WAW the PPSH-41 is by-far the best gun knows to ever COD ever. No other gun can even match up to it. It shred players and zombies in less that .5 of a millisecond. The sheer power on this gun is insane for a game thats based off of 1940's war.
