The 57 USG, sold as The Diplomat, is a high-capacity pistol from the Far Cry 6 online store. Its 20-round magazine and full set of mod sockets make it a flexible sidearm if you own it.
The large magazine makes it a forgiving sidearm. Fit a suppressor and it handles quiet base work. It is a good pick if you want a pistol that does not need reloading every few shots.
It is sold in the online store as The Diplomat. It is not part of the normal in-game unlock path.
It takes standard, armor-piercing, soft-target, poison, blast and incendiary rounds. Suppressor options include the Resolver Suppressor and its Mk. 2 upgrade, and you can add a laser pointer for better hip-fire.
.44 Magnum
The .44 Magnum is a six-shot revolver-style pistol that hits hard for a sidearm. Its two unique versions, Magnum, P.D. and The Big Dog, give you a quick-draw backup with real stopping power at short to mid range.
1911
The 1911 is a rare semi-automatic pistol in Far Cry 6, and one of the best all-round sidearms you can find. You unlock it through the And The Beat Goes On... treasure hunt, and it is Vaas's starting weapon in the Vaas: Insanity DLC.
