Description
The Sig Sauer P320 X-Five Legion 9mm 5″ TXG XGrip 3x10rd is a full-size, competition-ready pistol built for shooters who demand precision and control. Designed from the ground up for serious range work, it combines a 5-inch match barrel with a tungsten-infused TXG XGrip frame that reduces muzzle flip and speeds up follow-up shots. This pistol ships with three 10-round magazines, fiber-optic front sights, adjustable rear sights, and an optic-ready slide, making it a versatile choice for both iron-sight and red-dot shooters.

Key Features
- Tungsten-infused TXG XGrip frame — Why it matters: The added weight lowers the pistol’s center of gravity, reducing muzzle rise and helping you stay on target for faster, more accurate follow-up shots. This is a game-changer for competition shooters who need consistency round after round.
- 5-inch match-grade barrel — Why it matters: A precision-crafted barrel improves inherent accuracy, giving you tighter groups at distance. The longer sight radius also helps with sight alignment, making it easier to call your shots.
- Optic-ready slide with suppressor-height sights — Why it matters: You can mount your favorite red dot (like a Trijicon RMR or Leupold DeltaPoint Pro) without sending the slide to a gunsmith. The tall fiber-optic front and adjustable rear co-witness with most optics, so you’re never without a sight picture.
- Adjustable rear sight and fiber-optic front — Why it matters: Fine-tune your point of impact for different loads or distances. The fiber-optic front gathers light for a bright, fast sight picture in varied lighting conditions.
- Manual safety included — Why it matters: For shooters who prefer an added layer of security during transport or storage, the manual safety gives you peace of mind. It’s easily disengaged with your shooting thumb, so it won’t slow you down on the clock.
Who It’s For
This pistol is built for the competitive shooter who wants a factory-tuned platform ready for USPSA, IDPA, or steel challenge matches. It’s also an excellent choice for the dedicated range enthusiast who values precision and reduced recoil. Families teaching young or new shooters will appreciate the manual safety and the ability to start with iron sights and upgrade to a red dot later. If you’re looking for a 9mm handgun that rewards practice with tight groups and fast splits, the X-Five Legion is a strong contender.
Pros and Cons
- Pros: Extremely flat-shooting due to the heavy TXG grip; optic-ready without extra machining; adjustable rear sight for fine-tuning; comes with three magazines; reliable Sig Sauer build quality; manual safety for added safety.
- Cons: The weight (44.5 oz empty) may feel heavy for concealed carry or for shooters with smaller hands. The TXG grip texture can be aggressive for some, requiring gloves during extended range sessions.
