Handguns

Later named the Girardi ES9 through Grand Theft Auto VI's Ultimate Edition content page, this pistol is due to appear in the game and is described as based on the real-world Beretta 92FS. Protagonist Jason is shown firing it from inside a moving car in the game's second trailer around the 1:50 mark, and holding it while seated on a motorcycle in an official screenshot. The same Ultimate Edition reveal introduced a special engraved variant of the pistol for Jason alongside a matching special variant of the Klose K17 pistol for Lucia.

Shown officially Rockstar has shown this in a trailer, the Extended Look, an official screenshot, artwork, or its own site.
