Sig Sauer P220 Full Size Legion 45 ACP 4.4" 8+1 DA/SA Semi-Auto Pistol - R2

The Sig Sauer P220 Full Size Legion is a premium .45 ACP DA/SA service pistol and the flagship of SIG's Legion line - an enhanced version of the platform that launched the modern SIG Sauer family. This R2 configuration pairs a 4.4" barrel with a full-size 8+1 capacity, giving shooters a duty-grade .45 with classic P220 ergonomics and SIG's refined Legion trigger package.

The frame is finished in proprietary Legion Gray Elite Cerakote, a tough, low-glare coating that stands up to daily carry and hard use. An integral Picatinny accessory rail is molded into the dust cover for mounting weapon lights or lasers. The serrated slide is factory-cut to accept a Romeo 1 red-dot optic so you can mount a reflex sight with no additional machining.

SIG's XRAY3 Day/Night three-dot sight system rides on top of the slide, providing high-contrast aiming points for fast, intuitive target acquisition across a wide range of lighting conditions. A frame-mounted decocker lets the shooter safely drop the hammer without manipulating a manual safety, and the black G10 grips carry the signature Legion medallion for a secure, textured hold.

Chambered in .45 ACP, the P220 Full Size Legion R2 is at home as a duty sidearm, a home-defense handgun, or a premium range pistol that anchors any serious SIG collection.
