The standard SIG P226 incorporates a decocking lever on the left side of the frame above the magazine release button, which first appeared on the Sauer 38H prior to World War II, and allows the hammer to be dropped safely. In chambering or firing a round, the actuation of the slide automatically cocks the hammer. By using the decocking lever, the hammer can be de-cocked without actuating the firing pin disconnect, making it impossible to accidentally fire the weapon by using the decocking lever. Furthermore, using the decocking lever makes the weapon "drop safe," which means the firing pin will be blocked from striking a loaded round unless the trigger is pulled. Pulling the trigger and slowly lowering the hammer does not make the weapon "drop safe," and can result in an accidental discharge if sufficient force is applied to the hammer. Properly decocked, the pistol can be holstered safely and can be fired in double action mode by simply pulling the trigger. There is no manual safety to manipulate, as the SIG P226 incorporates only internal safeties. Double action trigger pressure is approximately 10 pounds. Subsequent shots are fired in single action mode with a lighter trigger pressure of approximately 4.4 pounds. As with other DA/SA pistols such as the HK USP and Beretta 92F, some training is required to minimize the difference in point of aim caused by the different trigger pressure between a first double action shot and subsequent single action shots. The hammer may also be manually cocked at any time by the user to fire in single action mode
