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.
 U.S. models
 Colt 6520 10mm 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 whom sophisticated high maintenance weapons would be a liability to survival.

 N99 10mm pistol
After the phase out of the N80 in 2051, the N99 sidearm became standard issue military gear. The N99 was known for its ability to survive in the harshest of conditions and did so in many tests, as 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 extreme 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 many units are available for replacement parts.

 Chinese models
 Shanxi Type 17 Chinese pistol
First produced in 1929 by the Taiyuan Arsenal, based on the Mauser C96 pistol, the Type 17 enjoyed renewed popularity as the standard sidearm of the People's Liberation Army during the Sino-American War. The Shanxi Type 17 is a recoil operated, locked breech semi-automatic pistol. The bolt and barrel are locked by a vertically tilting locking piece with two lugs locking into recesses beneath the bolt. It features an adjustable sight for up to 1000 meters. Unlike most modern pistols, the Shanxi Type 17 is loaded from a stripper clip into a fixed, non-removable box magazine.
 Zhu-Rong v418 Chinese pistol
The Zhu-Rong (project codename ZRIN) is a unique incendiary pistol, developed by L.O.B. Enterprises. Early prototype models attempted to use conventional 10mm shells housing a caplet containing amalgamating agents, intended to break upon impact and deliver a localized fireburst and shrapnel. However, in field tests the amalgam caplet ammunition proved too fragile, and several detonated from excessive vibration or walk speed.
The final version utilized an acumist coated barrel that delivers friction to the round, super-heating the projectile as it exits the weapon. This allowed the weapon to use standard 10mm rounds. The round would then fully liquefy on impact, burning the target. Additional retardant jacketing, as well as internal heat diffusers, prevented the user from receiving burns to the fingers and palm, when firing the weapon in rapid succession. The v418 (ZRIN-418) was the last version of the project development phase that was slated for final production.
