The weathered N99 10mm pistol is a weapon added by the Fallout: New Vegas add-on Courier's Stash or Classic Pack.


This section is transcluded from 10mm pistol. To change it, please edit the transcluded page.

The large-framed, gas-operated N99 was selected as the standard issue conventional sidearm of the United States military, following the phaseout of the N80 in 2051. The long-barreled pistol remained in service for 26 years, until the Great War destroyed the United States. The pistol is designed to withstand the most extreme conditions, which was one of the requirements for a new service sidearm. It can also be repaired easily by anyone with even the most basic technical knowledge. This includes both clearing misfeeds[1] and restoring a unit to working condition after long exposure to elements without maintenance.[2]

These features also make it popular with wastelanders, who appreciate the ease of maintenance. It remains a common weapon, as even though many civilian units were ruined, they can easily be restored by anyone with some repair knowledge. Even damaged units can be used reliably, though they will offer subpar performance and jam frequently. The number of manufactured pistols means that parts are easy to come by, however.[2]

Compared to the standard 10mm pistol, this weathered variant has cleaner and more subdued colors tending to gray. It does more damage than the standard 10mm pistol and is far more durable. In addition, it has no Guns skill requirement for accurate use, compared to a Guns skill of 25 for the standard model. However, despite the standard 10mm pistol being classified as a holdout weapon, this pistol is not. For a weapon obtained at the start of the game, this pistol is a powerful, reliable weapon in most cases.


The weathered 10mm pistol can fire a total of about 545 standard rounds, the equivalent of 46 reloads, or 35 reloads when modded with the extended magazines, from full condition before breaking.

    Pek: "Sure, I guess. Can you fix it?"
    The Lone Wanderer: "Sure can. Here, just pull this back to clear the chamber."
    Pek: "Wow... that's... that's easy. Now at least I can shoot back at those mutant bastards. Are you ready?"
