Sig Sauer P320 XFive Legion 9mm 5" MA Compliant

The P320 XFive Legion: Purpose-Built for Serious Shooters

Sig Sauer has engineered the P320 XFive Legion as a full-size handgun that combines modern materials science with proven ergonomics. This is not a minor variation on an existing design—it represents a significant step forward in polymer-framed pistol technology.

Weight and Recoil Management

The XFive Legion weighs 43.5 ounces, substantially more than standard P320 models. This additional mass comes from the innovative TXG grip module, which incorporates tungsten infusion. The result is a handgun that delivers the weight benefits of steel while maintaining the durability and flex of polymer. Shooters can expect up to 50% reduction in muzzle flip, translating directly to faster follow-up shots and improved accuracy.

Trigger and Action

The skeletonized flat trigger is approximately 30% lighter than conventional P320 triggers, promoting faster trigger reset and increased shooting speed without sacrificing control. The striker-fired action remains consistent with the P320 platform, ensuring familiarity for those already trained on the system.

Recoil System

The upgraded recoil assembly uses a solid steel guide rod paired with a 14-pound 1911-style spring. An additional 12-pound spring is included, allowing shooters to fine-tune the system to their preferences and ammunition choices.

Sights and Optics Compatibility

Dawson Precision fiber optic front and adjustable rear sights come standard, providing excellent visibility in varied lighting conditions. The slide is Romeo1PRO optic-ready, allowing seamless integration of modern red dot sights.

Ergonomics and Handling

The X-Series grip module features an extended beavertail, four-sided beveled magwell, and crisp trigger guard undercut. These refinements reduce hand fatigue and improve control during extended shooting sessions. The M1913 Picatinny rail accommodates lights, lasers, and other tactical accessories.
