Sig Sauer pistols are engineered to perform anywhere, at any time, and under any circumstance. They boast unique, advanced features that stand out among the rest. The P220 is the gun that started it all for modern day Sig, and is built to meet and exceed rigorous military standards. It features a stainless steel slide and a light-weight alloy frame with integral accessory rail. The Full Size Legion model is an enhanced version of the P220. It is finished in a proprietary Legion Gray PVD coating, custom G10 grips with a Legion medallion, Sig Sauer Electro-Optics X-RAY high visibility day/night sights, and comes with three magazines. It features a reduced, contoured Elite beavertail for higher grip with reduced profile; aggressive front strap checkering; an X-Five undercut with checkering under the trigger guard; front cocking serrations; and low profile decocking and slide catch levers.
