10mm pistol

10mm pistols are semi or fully-automatic handheld firearms that fire 10mm rounds. These sidearms appear in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout 4, Fallout 76 and Van Buren.

Background
10mm pistols are sidearms using the 10mm ammunition that was common before the Great War. They were used extensively by the Bureau of Alcohol, Drugs, Tobacco, Firearms and Lasers, while in the military such pistols were being phased out in favor of energy weapons. Their ruggedness, reliability and firepower made them a popular choice among wastelanders and thus a staple of wasteland firefights.

Colt 6520 pistol


 The Colt 6520 10mm autoloading pistol is a highly durable and efficient weapon developed by Colt Firearms prior to the Great War. It proved to be resistant to the desert-like conditions of the post-nuclear wasteland and is a fine example of workmanship and quality construction (at least for the pre-War models, which became more scarce over time). The simple design of the gun allows it to be easily manufactured with relatively basic equipment, making it possible to be replicated in workshops in the post-nuclear world. The Colt 6520's durability, reliability and simple design makes it very popular among wasteland denizens, for who sophisticated high maintenance weapons would be a liability to survival. 

N80 pistol
The 10mm N80 sidearm was standard issue military gear until it was phased out in 2051.

N99 pistol


 The large-framed 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 and restoring a unit to working condition after long exposure to elements without maintenance.

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. 

The N99 10mm pistol can be equipped with a suppressor. The benefit of the suppressor is that when one fires at an enemy and kills them with the first shot, no nearby enemies will be alerted. The downside for models in the Capital Wasteland is the slightly decreased damage compared to a regular N99, however silencers found in the Mojave Wasteland do not cause any performance issues.

Combat pistol
The 10mm combat pistol is a next-generation 10mm sidearm created before the Great War. While it is a different design from the N99, it can be transformed into something similar. One of the key differences is a slide release lever, automatically locking the slide back when the weapon runs dry.

Available to both government and civilian clients, the combat pistol could be fitted with an automatic receiver, turning it into a machine pistol, as well as a variety of optics (including high-tech recon scopes), suppressors and other accessories to improve its performance. At the same time, it remained a reliable, easily modified, and powerful workhorse of a sidearm, especially in the wasteland.
