The SIG Sauer P226 is a full-sized, service-type pistol made by SIG Sauer. This model is sold with a choice of four chambers to choose from: the 9×19mm Parabellum, .40 S&W, .357 SIG, or .22 Long Rifle. It has essentially the same basic design as the SIG Sauer P220, but is 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, while the P224 is a subcompact variant. The SIG Sauer P226 and its variants are in service with numerous law enforcement and military organizations worldwide.
