Mustang .357

Grand Theft Auto VI is scheduled to release on 19 November 2026. The Mustang .357 is a Duke Arms Company handgun identified as a revolver, with a listed 9.07mm caliber and a capacity of six rounds. Until release, public information on it is limited to Rockstar's trailers, official screenshots, and the August 2026 Extended Look. The available material gives no further description of its use.

One official screenshot provides the public image of the Mustang .357. A biker woman holds the revolver across her partner's chest, putting the weapon in view without showing it being fired or otherwise used. The image gives neither person a name, and the released material does not connect the screenshot to a named mission or story event.

The Duke Arms Company logo is visible behind the cylinder in that screenshot. The name Mustang .357 is engraved along the barrel, identifying the model in the image. Apart from these markings and the listed caliber and capacity, the public material does not say how the revolver is acquired or used in Grand Theft Auto VI.
