10mm Pistol (Fallout 3)

The N99 10mm Pistol is a small gun using the 10mm ammo, commonly found in Washington, DC and the surrounding Capital Wasteland. It is similar to the Colt 6520, which is more common on the West Coast. It is also the first real gun given to you in the game.

This weapon can be used to repair the Silenced 10mm Pistol.

Weapon Information Research Database File
The 10mm N99 sidearm was standard issue military gear following the phase out of the N80 in 2051. The N99 was known for its ability to survive in the harshest of conditions and in many tests, the weapon was able to reliably be restored to working condition after an extended period of time exposed to hard elements and without maintenance.

The N99 proved to stand up to its claims and as a result, is one of the most common weapons found in use in the Wasteland. While many civilian weapons were ruined beyond use in the exterior conditions following the war, the N99 is commonly able to be easily restored to working order by anyone with even the most basic knowledge of firearm mechanics.

However, an N99 in poor condition can often deliver low target and armor penetration, frequent jamming, and greatly reduced accuracy. Fortunately, the weapon was produced in great numbers and units are available for replacement parts.
