Design and key features

The SIG SAUER P320 XFIVE LEGION is a full-size, striker-fired semi-automatic built around a polymer frame with an innovative TXG tungsten-infused heavy XGrip module. That added mass — bringing the pistol to 43.5 oz — mimics the damping benefits of steel while retaining polymer’s ergonomics. The result is up to 50% less muzzle flip in controlled testing and markedly faster follow-up shots.

Trigger, recoil system, and controls

Factory enhancements include a skeletonized flat trigger that yields a pull up to 30% lighter compared with baseline P320 triggers, promoting faster splits and cleaner resets. The recoil system uses a solid steel guide rod and a 14 lb 1911-style spring, with an extra 12 lb spring included for tuning. Other user-forward touches: a flared magwell, optics-ready slide compatible with the included SIG Romeo1PRO optic in the factory box, and Dawson Precision fiber optic front sight with an adjustable rear sight.

Slide, barrel, and finish

The 5″ bull barrel paired with the Legion Gray PVD slide with lightening cuts improves balance and sight radius, while optic-ready cuts simplify mounting a red dot. Standard capacity is 17 rounds, and the package ships with multiple magazines to support range sessions and competitive use.

Caliber, magazines, and practical applications

The SIG SAUER P320 XFIVE LEGION is chambered in 9mm — a versatile choice that balances recoil management, magazine capacity, and ammunition availability. The standard 17-round magazine offers ample capacity for training and duty use; the kit also includes additional magazines (including higher-capacity options) for extended practice or competition formats. For anyone focused on rapid, accurate strings in USPSA/IDPA or high-volume range time, the 9mm XFIVE Legion is optimized for consistent performance.

Why experienced shooters choose it

Between the tungsten-infused XGrip, skeletonized flat trigger, upgraded recoil spring system, optics-ready slide, and premium sights, the SIG SAUER P320 XFIVE LEGION is engineered for shooters who demand speed and precision. At a street price around $999.99, it competes in value against other high-end competition-ready pistols while delivering a unique blend of weight, ergonomics, and factory accessories.
