.45 AP Silencer

 is a weapon mod for the .45 Auto pistol in the Fallout: New Vegas add-on Honest Hearts.

Effects
Attaches a silencer to the barrel of the .45 Auto pistol which reduces noise generated by firing the weapon. A slight downside is that it slightly obstructs the player's view while aiming, this isn't usually a problem, however it can be somewhat detrimental to your accuracy at longer ranges.

Locations

 * Can be purchased from Joshua Graham in Angel Cave.
 * Can be purchased at the Gun Runners (with the Honest Hearts add-on installed).

Behind the Scenes
The suppressed gunfire shares the same sound emission with the Infiltrator and Perforator
