The SIG Sauer P226 is a full-sized, service-type pistol made by SIG Sauer. It is chambered for the 919mm Parabellum, .40 S&W, .357 SIG, and .22 Long Rifle. It is essentially the same basic design of the SIG Sauer P220, but developed to use higher capacity, double stack magazines in place of the single stack magazines of the P220. The P226 itself has spawned further sub-variants; the P228 and P229 are both compact versions of the double stack P226 design. The SIG Sauer P226 and its variants are in service with numerous law enforcement and military organizations worldwide.
