I would feel a lot safer about the eventual zombie apocalypse if both the police and the military were armed with the DoubleStar Zombie-X AK-47. This zombie-killing weapon is a combination of an AK-47 and an electric chainsaw and is guaranteed to stop a zombie in its tracks.
The DoubleStar Zombie-X AK-47 isn't just designed for show; this gun means serious business. This modified AK has a drum magazine and a holographic sight complete with a bio-hazard symbol as the reticule. The electric chainsaw is mounted at the barrel of the gun and is the perfect length for a melee weapon. DoubleStar's previous and less awesome zombie killer, the DSC Zombie Slayer, sold for $1,249, so it's reasonable to expect pricing slightly higher.
