SIG SAUER P226 LEGION 9MM 15RD 4.4″ PISTOL W/ ROMEO1 PRO – E26R-9-LEGION-RXP

The Legion P226 Legion RX is equipped with a slide-mounted reflex optic, the ROMEO1. All of the benefits of the P226 Legion are enhanced through the use of SIG SAUER’s premier line of reflex mounted pistol optics. Shoot confidently and enjoy the crisp reliability of the P226’s smooth double-action/single-action trigger. With the ROMEO1, this P226 Legion RX is the perfect mix of versatility and performance.

The Legion P226 is finished in Cerakote® Elite Legion gray coating, custom G-10 grips with a Legion medallion, the SIG SAUER Electro-Optics X-RAY high visibility day/night sights comes with three magazines. The P226 in DA/SA includes a reduced and contoured Elite beavertail, which allows for a higher grip, but a reduced profile, thus eliminating printing. More aggressive front strap checkering and additional checkering under the trigger guard enhance the grip. An X-Five undercut has been applied to the trigger guard, allowing for a higher grip and greater control. Front cocking serrations provide greater purchase for cycling the action, clearing the firearm, or conducting press checks. The DA/SA is available in 9 mm, .40 and .357 SIG. The DA/SA also features low profile decocking and slide catch levers to reduce the risk of snagging. An enhanced polished action with the SRT (Short-Reset Trigger) is augmented with a Grayguns, Inc. designed P-SAIT trigger. In addition, a solid steel guide rod adds weight where it matters most.

1. The Heritage of the SIG SAUER P226

Before diving into the LEGION RXP upgrades, it’s important to appreciate the history of the P226 platform. Originally developed in the 1980s as SIG’s entry in the U.S. military’s XM9 trials, the P226 was built to withstand the most rigorous testing in the world.

While the Beretta M9 ultimately won the military contract, the P226 quickly became the choice of elite military units such as the U.S. Navy SEALs, British SAS, and numerous law enforcement agencies worldwide. Its combat-proven track record, combined with superior ergonomics and unmatched reliability, cemented its status as one of the most respected duty pistols ever produced.

The LEGION Series takes that battle-tested platform and enhances it for the most demanding shooters of today.
