Frequently Asked Questions

What is the historical origin of the Sig Sauer P220?

The Sig Sauer P220's design began in 1975 when the Swiss Army sought to replace their P210 pistols with a more modern double-action/single-action combat firearm. This led to the development of the 9x19mm P220 model.

What are the key safety features of the Sig Sauer P220?

The P220 features a side-mounted de-cocker and a critical firing pin safety. The firing pin safety prevents forward movement of the firing pin unless the trigger is pulled completely to the rear, ensuring the pistol cannot fire accidentally.

What are the technical specifications of the Sig P220 Nitron 45 ACP?

The P220 Nitron has a 4.4-inch barrel, 7.7-inch overall length, 1.5-inch width, 5.5-inch height, and weighs 30.4 ounces. It features an aluminum alloy frame and a stainless steel slide with a 1913 rail.

How does the P220's trigger system work?

The P220 utilizes a double-action/single-action (DA/SA) trigger. The first shot is a long, heavier double-action pull. After the first shot, the hammer is cocked, and subsequent shots use a shorter, lighter single-action pull.
