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.
