Call of Duty: Black Ops DS
The Mk. 22. Mod. 0 appears in Black Ops DS. It is the allied side arm of choice and always has a silencer on it making for silenced kills. The Mk. 22 is the secondary weapon in every SOG mission and can kill with two shots at close ranges or three if the target is far away; it has an 8 round magazine and relatively fast reload. It is one of the few weapons that does not appears in the Zombie version (unless downed); in Multiplayer it is preunlocked for the allied faction, and making 150 kills with the Mk. 22 will unlock the M10.

Trivia

 * Supposedly, the original version of MK 22 uses a slide lock to enhance suppression effect, and the user has to rack the slide to load another round, thus it's not semi automatic. However, it may be a custom MK 22.
 * It is nicknamed the "Hush Puppy" due to its use in Vietnam to stealthily kill guard dogs.
 * The gun is based on the real life Smith & Wesson Mk 22 Model 0, a variant of the Smith & Wesson Model 39, which is somewhat similar in appearance to the M1911.
 * In Zombies, the player uses this pistol when downed.
 * Also in Zombies, a glitch can occur when the player fires off all rounds of their Makarov; if the player has no other weapon, they will automatically receive a Mk. 22 Mod. 0, at no cost in points.
