10mm Pistol

The wasteland's most reliable sidearm for every survivor.

The 10mm pistol is a semi-automatic handgun that serves as one of the most recognizable firearms in the post-apocalyptic Commonwealth and surrounding regions. Originally designed before the Great War for military and law enforcement use, its durability and ammunition availability ensured its survival through centuries of decay. Throughout the various conflicts following the nuclear exchange, this weapon became a standard issue sidearm for numerous factions due to its manageable recoil and reliable mechanical action.

Lore & Background

Before the bombs fell, the 10mm pistol was favored by security forces and military personnel who required a compact weapon with stopping power superior to standard .38 caliber revolvers. Its design prioritized mass production and ease of maintenance, qualities that proved invaluable when industrial supply chains collapsed. In the post-war era, factions like the New California Republic adopted it as a primary sidearm for their rangers and soldiers because 10mm rounds were easier to manufacture than larger calibers. The Brotherhood of Steel also utilizes variants of this design, often modifying them with advanced optics or suppressors to suit their tactical doctrines. Despite its age, the weapon's engineering remains robust enough to withstand the harsh environmental conditions of the wasteland. It is frequently found in the hands of scavengers and merchants who trade it as a standard currency for protection.

In Their Own Story

The dust coated every surface of the old armory, but the metal gleamed under the flickering lantern light. He picked up the pistol, feeling its weight settle comfortably into his palm. It was cold, dead steel until he racked the slide, the sound echoing sharply in the silence. A single round clicked home. Out there, beyond the ruined walls, something waited for him to make a mistake. This gun would be the only thing standing between him and the dark.

Reader's Guide

The 10mm pistol functions as a reliable mid-range sidearm for wasteland travelers seeking consistent firepower without the bulk of rifles. Historically, this weapon traces its lineage to pre-war military specifications, designed for easy mass production and maintenance under harsh conditions. In the games, it is frequently found in the hands of early-game enemies or purchased from general merchants across various settlements like Diamond City or Goodsprings. Acquisition often involves scavenging from fallen raiders or completing introductory quests that reward basic weaponry. Its significance lies in its balance; while not as powerful as heavy revolvers, it offers a higher rate of fire and magazine capacity compared to single-shot alternatives. Craftsmen can modify the frame to accept scopes or suppressors, enhancing utility for stealth or precision engagements against dangerous mutants. For new survivors, securing a 10mm pistol is often the first step toward establishing self-defense capabilities in the dangerous ruins of the old world. Ammunition remains relatively common compared to larger calibers, making it a sustainable choice for prolonged expeditions through hostile territories.
