The Mysterious Magnum is a .44 Magnum revolver that plays the Mysterious Stranger's theme whenever it is drawn or holstered. This revolver features a silver finish with intricate engravings etched all around the weapon, a pearlescent grip, higher damage, and a significantly faster firing rate than a normal .44 Magnum. It can also be concealed so long as one's Sneakskill is at least 50, making it an improved holdout weapon. Like most unique weapons, weapon modifications cannot be used on the Mysterious Magnum.
If the Mysterious Magnum is given to a companion, the Stranger's theme will play when they use it.
Holstering it will make the second part of the tune play.
Drawing/Holstering the weapon while sneaking will cause the tune to play softly, thus not giving away one's position to enemies. The enemy seems to never hear this tune while the player character remains hidden.
It has a greatly reduced item HP compared to the standard .44 Magnum revolver, meaning that it will need to be repaired more often.

PC When you use .44 Magnum or the Mysterious Magnum in 3rd person view, most of the time you will miss the target, even while you're aiming, therefore making it better to use this gun in 1st person view. [verified]
PC Occasionally, when the Mysterious Magnum is equipped, the speed loader of the weapon can be seen stuck to the back of the cylinder and protruding from the back of the gun. This glitch has no effect on gameplay, as it is merely cosmetic. It can be fixed by un-equipping it and re-equipping it, reloading it or switching ammunition types. It also happens with the regular .44 Magnum, especially with the Heavy Frame. [verified]
