NIPPER .38

The Nipper .38 is a smaller-caliber revolver named directly in GTA 6 trailer footage, positioned as a lighter sidearm relative to the higher-caliber Mustang .357 also confirmed for the game. In real firearms terms, a .38 round is generally easier to control and faster to follow up with a second shot than a .357 Magnum, which historically has translated in GTA games to revolvers like this filling an early, accessible-sidearm role rather than a heavy-hitting option.
