Section 2: A New Standard in Competitive Pistol Performance

Legion Gray Finish and Tactical Look

The Legion Gray PVD finish is not just visually stunning—it’s designed for durability and corrosion resistance. This signature look separates the Legion series from standard black or stainless pistols, giving it a unique tactical edge that looks serious and performs even more seriously.

TXG Grip Module – A Game-Changer

At the heart of the XFIVE Legion’s outstanding balance is its revolutionary TXG (Tungsten-Infused Polymer) Grip Module. SIG SAUER is the first manufacturer to successfully combine polymer and tungsten in one solid, monolithic grip. This gives the pistol a steel-like weight distribution (43.5 oz) while maintaining the comfort and customization of polymer grips.

The added mass in the grip dramatically reduces muzzle rise and perceived recoil, allowing for faster follow-up shots, tighter groupings, and less shooter fatigue.

Flat-Faced Skeletonized Trigger

The XFIVE Legion’s flat-face trigger is both visually aggressive and functionally superior. It breaks cleanly and crisply at a short travel point, enabling shooters to deliver rapid and precise fire with minimal effort. This is not a standard P320 trigger—it’s engineered for speed and consistency. The lightened trigger pull (approximately 4.5–5 lbs) supports better control in match conditions.

Section 3: Sight System and Optics Compatibility

Dawson Precision Fiber Optic Front Sight

In high-speed shooting competitions, sight clarity and visibility are key. That’s why the XFIVE Legion comes with Dawson Precision® Fiber Optic front sights, known for their brightness and fast target acquisition. Whether you’re at the range under bright daylight or low light indoors, these sights keep you locked in on target.

Fully Adjustable Rear Sight Plate

The rear sight is mounted on a removable optics plate, which allows you to install red dot sights like the SIG SAUER ROMEO1PRO, Leupold DeltaPoint Pro, or Trijicon RMR. Once a red dot is mounted, the shooter can transition to faster target acquisition, increasing speed and effectiveness in competition or tactical scenarios.

Section 4: Accuracy, Control, and Customization

Weighted Guide Rod and Recoil Springs

SIG includes a solid steel guide rod with interchangeable recoil springs to let you fine-tune the recoil characteristics to your ammo and shooting style. This level of personalization is rare in striker-fired pistols and reinforces the XFIVE Legion’s elite status.

Trigger Guard Undercut and Beavertail

For enhanced grip and control, the grip module features a high beavertail and an undercut trigger guard. These design choices encourage a higher hand position, reducing muzzle flip and improving sight return.

Aggressive Texturing and Grip Geometry

The XFIVE Legion doesn’t just feel right—it stays glued to your hand under stress. The aggressive yet comfortable grip texture ensures confident handling during extended shooting sessions. The removable magwell and extended magazine baseplates also make fast reloads seamless.

---

Section 5: Ideal Use Cases

1. Competitive Shooting

This is where the XFIVE Legion shines. Whether it’s USPSA, IDPA, or 3-Gun, this pistol was built with serious shooters in mind. The combination of weight, recoil control, and fast trigger reset makes it one of the best factory competition pistols available.

2. Tactical Training and Law Enforcement

While built for competition, the XFIVE Legion is also an excellent tool for tactical drills and training environments. Its heavy frame and consistent performance make it ideal for refining shooting fundamentals.

3. Home Defense

Some gun owners prefer a heavier full-size pistol for home defense. The 17+1 capacity, paired with superb accuracy and stability, makes this firearm a viable choice for defending your home with precision and control.

4. Enthusiast and Collector Appeal

With the Legion series’ premium materials, finish, and engineering, this firearm is a must-have for SIG fans and collectors. Owning one is more than just a purchase—it’s entry into an elite club of performance-minded shooters.

---

Section 6: Magazine Capacity and Reload Efficiency

Included with the XFIVE Legion are three (3) 17-round steel magazines with aluminum Henning Group-style baseplates. These not only offer a slight grip extension for larger hands but also assist in fast reloads under pressure. The pistol also accepts extended capacity magazines for range or competition use.

---

Section 7: Accessory Compatibility and Modularity

M1913 Picatinny Rail

The full-length Picatinny rail supports a range of accessories including:

• Tactical weapon lights (e.g., SureFire X300, Streamlight TLR-1)

• Laser sights

• Combo devices for low-light shooting

Modular Fire Control Unit (FCU)

Being part of the P320 family, the XFIVE Legion’s FCU is modular—you can legally swap the trigger group into other compatible grip modules, calibers, and configurations. This modularity is a game-changer for shooters who want to adapt to different missions or competitions.

---

Section 8: Legion Membership and Exclusive Benefits

When you purchase a Legion firearm, you get automatic access to the SIG Legion program, which includes:

• Exclusive Legion-branded gear

• Legion members-only training videos and merchandise

• Limited edition cases and challenge coins
