The SIG P228 is a compact pistol in the SIG P220 family. The P228, designated M11 by the US military, is used primarily by US Army CID and US Navy and Marine Corps aviators. A suppressed P228 is John Bradley's sidearm in Conflict: Desert Storm and its direct sequel. In missions requiring stealth, Mick Connors will also use one instead of his regular sidearm. In Conflict: Global Terror, however, Bradley has ceased using it and now carries a Heckler & Koch MK23 Mod 0.
- The SIG P228 is based on the real life SIG Sauer P228 (M11) handgun chambered only in 9x19mm Parabellum.
