The SIG Sauer P320 X-Five Legion is a full-size 9mm competition pistol with a 5-inch barrel and 8.5-inch overall length. Three 10-round magazines are included. The Legion Gray finish and tungsten-infused XGrip module are distinctive -- and the added mass from the tungsten grip module meaningfully reduces felt recoil during rapid fire.

Features 

The striker-fired action has a consistent pull with short travel. The skeletonized trigger reduces pull weight without adding unsafe play. Fiber optic front and adjustable rear sights cover most lighting situations; the optics-ready cut lets you mount a red dot directly. The XGrip module is modular, so swapping to fit different hand sizes is straightforward. 
 

Who It's For 

The X-Five Legion is aimed squarely at IPSC/USPSA competitors and serious range shooters who need consistent accuracy at speed. Its 5-inch barrel and weight profile make it less suited for daily concealed carry, but for anyone who prioritizes precision in an open or limited division, it fits well. It also works as a home defense option if weight is not a concern.

Owners of the Sig Sauer P320 X-Five Legion 9mm tend to rate it highly for competition use, though a few consistent trade-offs come up across discussions.

Accuracy is the top selling point. The 5-inch barrel and heavier weight make the gun very stable during fast strings, and most users see it immediately in their groupings. The ergonomics also get strong marks -- the grip fits a wide range of hands and the overall balance is considered excellent for extended range work. The optics-ready design comes up often as a practical plus; mounting a red dot is simple and it's become a common configuration. Build quality is consistently praised, with the materials feeling solid and well-fitted.

The weight is the most common criticism. At 43.5 oz unloaded, this is not a light gun, and users who expected a versatile carry-plus-competition option typically note it's not comfortable for EDC. Price is another friction point -- the Legion premium is real, and some buyers feel there are capable competitors for less. Trigger feel draws mixed reactions; most find it good, but a portion of shooters find the pull weight or travel distance not to their preference, particularly compared to aftermarket-tuned options. Magazine capacity also comes up -- 10+1 is a California-legal configuration and some users outside restricted states would prefer standard higher-capacity magazines.

For competition shooting, this is one of the better out-of-the-box options in the P320 line. If you're primarily running it at the range or in matches, the weight is actually an asset. If daily carry is part of the plan, weight and bulk should factor into the decision.
