Sig-Sauer P220 Handgun w/ Silencer or SG220.S, is a small, lightweight pistol fitted with a suppressor.
It notably lacks stopping power and range, due to the light 9x19mm Parabellum rounds and the suppressor.
- Asylum Aftermath: found on a SWAT Team Member, near a police car outside.
- The Bjarkhov Bomb: found on a desk in Sergei Bjarkhov's office.
- Traditions of the Trade: found on a desk near the bathroom where Frantz Fuchs is showering.

- The Sig-Sauer P220's magazine can carry 8 rounds of 9mm Parabellum in real life, but only 7 rounds in game, although the .45 caliber version of the P220 can carry 7 rounds.
- The player can obtain the dual-wielded version by beating Traditions of the Trade with a Silent Assassin rating.
- Oddly enough, the regular SG 220 has no hammer, but the dual-wielded version has them.
