Dirty Harry

THE HOLY PISTOL IS REAL. READ THE TRIVIA SECTION. Next idiot that says its fake is going to get blocked.

The Holy Pistol is a weapon found in Call of Duty: World at War and Call of Duty: Black Ops. It is only available through cheats on the PC version of the game or through hacks on the console versions.

Call of Duty: World at War
The Holy Pistol is essentially an M1911 that shoots rifle grenades. It fires the same way as the player's pistol does when downed and the Suicide King Death Card is enabled. The player can also acquire it through the console on PC. Two similar weapons, the C-3000 and Mustang and Sally, are Pack-a-Punched pistols that act similarly, but are semi-automatic, give splash damage, and fire in a straight line instead of an arc.

Call of Duty: Black Ops
In Black Ops, the Holy Pistol functions similarly to the World at War version, or a pack-a-punched M1911. It can be found by using the "give all" command. Upon entering the command, the user will receive all guns, which includes 2 "Mustang & Sallys". The first one operates as normal, but upon equipping the second one, the left hand pistol will dissapear, and only the right hand pistol is usable, although the left trigger will still fire an extra grenade out of the single pistol. Since it is a one-handed grenade shooting pistol, it can be inferred that this is "holy pistol" of Black Ops.

Trivia

 * Due to the fact that the weapon was never meant to be used, several graphical quirks exist with this weapon. For instance, when sprinting with this weapon, the player holds the weapon down as if they were using a M1 Garand with rifle grenade. The reloading animation is the same for empty and non-empty magazines. Also, from third person, the player appears to throw a grenade whenever the weapon is fired.
 * This weapon's file name is "colt_dirty_harry" referring to the movie Dirty Harry.
 * The Holy Pistol takes much longer to look through the sights than the M1911.
 * While using the Holy Pistol, the player's left hand fingers are colored in red.
 * When you have the Holy Pistol out, you cannot melee. Having the Bowie Knife doesn't change this.
 * In Black Ops, firing the Holy Pistol takes much longer for the projectile to reach it's target, and the grenades are invisible. Also, the players arms are not visible, only leaving the gun for you to see.
