The Jackdaw is a unique flintlock pistol in Far Cry 6 that you can only get from the Buccaneer Pack in the online store. Its description jokes that each shot makes three holes.
Buy the Buccaneer Pack in the online store. It is not found anywhere in the open world.
It is mostly a cosmetic pick for players who like the pirate theme. Treat it as a sidearm and compare it with the pistols you already own before relying on it.
.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.
57 USG
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.
6P13 Auto
The 6P13 Auto is a fully automatic machine pistol with a 40-round drum. It sprays fast at close range, and its unique versions come from Los Bandidos operations and two insurgencies.
