Silenced 10mm Pistol

The Silenced 10mm Pistol is a Fallout 3 weapon. It is a 10mm Pistol equipped with a suppressor. The benefit of the suppressor is that when you fire on an enemy and kill them in the first salvo (say, using VATS while hidden), no nearby enemies will be alerted. But the down side is the slightly less damage it does. If you do not kill your target in the first salvo, they will likely alert nearby enemies. It is a great weapon for assassin-type characters, a good sneak and small guns skill will give you an advantage when sneaking while using this weapon.

Regular 10mm Pistols can be used to repair the Silenced 10mm Pistol.

Caution! Be careful to not repair a regular 10mm Pistol with the Silenced 10mm, as they may be hard to find. (I have never seen a common enemy other than ghouls in the underworld using this weapon!)

The only other ranged silent weapon is the Dart Gun, which is a custom weapon.

Locations
One is wielded by Mr. Burke in Megaton or Tenpenny Tower. Another can be found in Marigold Metro Station, which is part of the quest Those! A third Silenced 10mm Pistol can be found in the caves under Oasis. One may or may not appear in a locked safe(very easy) in one of the ruined houses in Springvale. One can be found in a locked safe in a room near the entrance of the museum of history's lower halls. Some Ghoul residents of Underworld also carry this gun. Rarely, it can be purchased at Flak and Shrapel's weapon store in Rivet City. Another can be found in a safe located in an unmarked sewer located south east from Arlington Library. It is also seen in the entrance to Vault 108
