The .380 Compact Auto is the modern descendant of the 9x17mm/.380 ACP, a cartridge that spent two centuries occupying the ceiling of what a truly compact semi-automatic pistol could chamber. By 2200 it has been pushed upmarket by the downward drift of 9x19mm platforms into ever-smaller form factors, but it has not disappeared. Instead it has found a firm niche as the preferred round of GLMZ's mid-tier concealed carry market: people in Tier 2-3 access zones who want genuine defensive capability in something that clears a fabric scanner without triggering secondary inspection. Slagworks, Meridian Arms (no relation to the dissolved PD), and a half-dozen gray-market manufacturers all produce brass-cased .380 CA, and the caseless variant has achieved modest penetration in higher-end compact platforms.

What sets the .380 CA apart in 2200 from its ancestor is the projectile technology. Standard production rounds now ship with either semi-jacketed expanding profiles optimized for unaugmented targets or dense tungsten-composite solids aimed at the subdermal plating increasingly common in Tier 2 and above. The street name 'Short Nine' is both a technical description and a mild insult — the implication being that you couldn't handle the full 9x19mm. Most people who carry .380 CA ignore this. They know what it can do, and they know that in the corridors and transit tubes and mid-tier arcology lobbies where they spend their lives, it is more than enough.
