Product Overview

The Sig Sauer P220 Nitron is a full-size .45 ACP semi-automatic pistol built on decades of proven combat and law-enforcement service. Since its introduction in 1976, the P220 has earned a reputation as one of the most naturally accurate .45s you can take from the box—a trait that still holds true today. Whether you're looking for a reliable duty sidearm, a serious defense pistol, or a straight-shooting range gun, the P220 Nitron combines precision engineering with genuine stopping power in a platform trusted worldwide.

The pistol's design reflects Sig Sauer's commitment to both durability and shootability. A stainless steel slide, machined from barstock and finished in the company's hard-wearing Nitron coating, pairs with a lightweight alloy frame that keeps the gun manageable without sacrificing control. An integral accessory rail lets you mount lights or lasers, and the four-point safety system—decocking lever, automatic firing pin safety block, safety intercept notch, and trigger bar disconnector—gives you layered confidence on the draw and in the holster.

The DA/SA trigger action delivers a 10-pound double-action pull for safe, deliberate first shots and a crisp 4.4-pound single-action break for follow-ups. At 7.70 inches long and just under 1.5 inches wide, it carries naturally in duty rigs and concealment holsters alike. Eight rounds of .45 ACP ride in the magazine, and the 6.30-inch sight radius supports both combat accuracy and precision work. Black polymer grips and SIGLITE night sights (available) round out a package that performs in daylight or darkness.
