SIG Sauer P226 MK25

The MK25 is a full-sized combat pistol, featuring the same double-action/single-action (DA/SA) trigger decocking action as the standard P226 and other SIG pistols of the same basic design. Once loaded, the first shot is fired using a long DA trigger pull. The pull weighs in at 10 pounds, 8 ounces according to my Wheeler Engineering Trigger Gauge. Once the first shot is fired, the slide cycles automatically and cocks the external hammer, moving it to the single-action firing position. Single-action weighs in at a greatly reduced 3 pounds, 14 ounces. The MK25 will continue to fire in single-action until empty or until the user presses the decocking lever located on the left side of the receiver above the magazine release. The SIG decocking levers do not additionally function as manual safeties like the Beretta 92 or Walther PPK decocking levers do. The long trigger pull of the first shot acts as the safety feature for SIG pistols of this type. Never carry DA/SA SIG pistols with the external hammer cocked.
