Sig Sauer P320 320X59Legionmsca*Ca*P320 9Mm 5 Or 10R Blk

The Sig Sauer P320 X-FIVE LEGION is a full-size, competition-ready 9mm pistol built for shooters who demand precision, control, and reliability in a duty or match gun. This California-compliant striker-fired pistol combines modular engineering with purpose-built components designed to minimize recoil and improve shot placement—whether you're running a match, training hard at the range, or carrying professionally.

What sets the X-FIVE LEGION apart is its tungsten-infused grip module, which brings the overall weight to 43.5 oz. That mass absorbs recoil energy, helping you recover faster between shots and stay on target. The skeletonized flat trigger is lighter and faster than standard fare, and the recoil system uses a solid steel guide rod paired with dual springs—a 14 lb mainspring with an additional 12 lb spring included—to manage the 9mm round smoothly. The 5-inch match-grade bull barrel and optic-ready slide (RX footprint, DeltaPoint Pro compatible) give you the foundation for a serious shooting platform.

You get three 10-round steel magazines with Henning Group anodized alloy basepads, Dawson Precision fiber optic front and adjustable rear sights, and a removable magwell for a customized grip. The LEGION Gray Cerakote finish and LEGION markings on the slide and sight plate reinforce the professional pedigree. Manual safety is included, and a loaded chamber indicator keeps you aware of gun state. With an 8.5-inch overall length, 6.8-inch sight radius, and M1913 accessory rail, the X-FIVE LEGION is sized and equipped for serious shooters.

Frequently Asked Questions

What makes the P320 X-FIVE LEGION heavier than a standard P320?

The tungsten-infused grip module is the primary weight contributor, bringing the pistol to 43.5 oz loaded. Tungsten is denser than steel, so it adds mass without significantly increasing size. That weight helps absorb recoil and reduces muzzle flip, making follow-up shots faster and more controlled.

Can I mount an optic on this pistol?

Yes. The P320 X-FIVE LEGION has an optic-ready slide with DeltaPoint Pro / RX footprint milling. The pistol ships without an optic installed, so you'll need to source one separately if you want to run a red dot.

Is this pistol California-legal?

Yes, this model is California-compliant as configured, with a manual safety and 10-round magazine capacity. Verify any local or state restrictions before purchase.

What magazines come with the P320 X-FIVE LEGION?

Three 10-round steel magazines with Henning Group anodized alloy LEGION basepads are included.
