Rainbow Six Wiki
Overview Siege

"Semi-automatic pistol with low-caliber, high-velocity rounds. Used by FBI SWAT."
— In-game description

The 5.7 USG is a weapon featured in Tom Clancy's Rainbow Six Siege. It is available for use by all FBI SWAT Operators, Nøkk, and Zero.[1]


The 5.7 USG is a handgun that sacrifices damage for having the highest magazine capacity of all handguns. It also has a decent hip fire accuracy. While its high capacity does increase room for error, it's relatively sub-par in close-range engagements due to its somewhat underwhelming damage.

Zero's 5.7 USG comes pre-attached with a Suppressor, and cannot equip a different muzzle attachment.


  • High magazine capacity


  • Subpar damage output
  • Low reserve ammo

Learning Area[]

There are two Situations where a 5.7 USG is wielded. The Suburban Extraction Situation has an FBI SWAT Recruit equipped with an R4-C and a 5.7 USG as a sidearm. The Tubular Assault Situation has the Operator Ash equipped with a G36C and a 5.7 USG. In Both Situations, the 5.7 USG is equipped with the Muzzle Brake.




Suppressed (Zero Only)[]


  • Despite its name implying that the weapon is the USG model, the 5.7 USG is actually based on the Mk 2 model, due to the cocking serrations at the front of the slide.
  • The 5.7 USG and the GSh-18 are the only pistols in Siege capable of destroying a standard barricade without reloading.
