The MK23 is a pistol that was introduced during the Summer Sideshow 2012 event. It is comparable to the 9mm tactical pistol in terms of speed, accuracy, recoil and ammo capacity, while dealing significantly higher damage and gaining the ability to shoot through up to three targets. It weighs the same as the .44 Magnum and the Handcannon, but deals lower damage than they do. The MK23 can be dual-wielded, doubling its magazine capacity and increasing its rate of fire, at the expense of accuracy. Dual-wielding does not increase reserve ammo capacity and gives this weapon a very long reload time.


The Sharpshooter perk receives a discount on MK23 from the Trader. Its base damage is 82 with a headshot multiplier of 1.1.

  • A single MK23 weighs just 2 blocks, an attribute shared by all pistols. This makes this weapon an excellent choice as an off-perk sidearm, especially when weight is a concern.
  • Its ability to damage three targets in a row coupled with its ammo capacity and speed makes this pistol somewhat more apt at fending off small groups of zeds than the others.
  • When used by a skilled Sharpshooter, it can be used as a decent Primary weapon in the first few waves. With it's low price, combined very well balanced knockdown power and magazine size, it's a great sidearm to invest in early on.
