Jason's Girardi ES9 and Lucia's Klose K17
Both leads get a named, personally engraved sidearm. The naming tells you more than the engraving does.

The Ultimate Edition includes personalised sidearms for both leads: a Girardi ES9 for Jason and a Klose K17 for Lucia, both with detailed engraving.
Why the names matter
This is the first time Rockstar has given Grand Theft Auto 6 firearms full manufacturer-and-model names in official copy. Everything else circulating is a community identification off a trailer frame, which is why our weapons list is so short.
Two named manufacturers is a small thing that tells you the game has a proper firearms catalogue behind it, structured the way the vehicle catalogue is, with brands that will recur.
A sidearm each is a design statement
Grand Theft Auto V gave its three protagonists special abilities and an identical arsenal. Giving Jason and Lucia a distinct named pistol each, rather than a shared pool, fits a game built around switching between two people whose relationship is itself a tracked system.
It also fits the carry limit. If a sidearm is the one weapon that is always on you, then the sidearm is the character's weapon in a way no rifle in a boot will ever be.
What the shot shows
Two pistols laid out on a table, one plain and black, one in red and chrome with heavy engraving across the slide and grip. Rockstar has not labelled which is which in the image, so we are not going to guess.
What is not known
Which pistol in the image belongs to which character, whether the ES9 and K17 exist in plain form in the base game, and whether engraving is purely cosmetic or interacts with weapon condition and the evidence system.
