The SIG Sauer P226 is a full-sized service pistol made by SIG Sauer. This model is available in four chamberings: the 9×19mm Parabellum, .40 S&W, .357 SIG, or .22 Long Rifle. It has the same mechanism of operation 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.
