In-Depth Technical Review

Tungsten-Infused TXG Grip Module

What truly sets the SIG P320 X CARRY LEGION apart is its tungsten-infused polymer grip module. By combining the durability of polymer with the weight and recoil-dampening properties of tungsten, SIG has created a revolutionary hybrid grip that drastically reduces muzzle rise, enhances balance, and enables faster, more accurate follow-up shots. At approximately 43.5 oz fully loaded, this firearm maintains the recoil profile of a full-size steel pistol while preserving compact dimensions.

The grip features a deeply undercut trigger guard, high beavertail, and aggressive stippling—ensuring a locked-in grip during rapid fire or adverse conditions.

---

X-Series Flat Trigger

SIG’s flat-faced X-Series trigger is engineered for precision. With a crisp 90-degree break and a short reset, the trigger system provides consistent feedback shot after shot. The design encourages a straight pull-back motion, reducing lateral force and increasing trigger control under pressure.

---

Suppressor-Ready Threaded Barrel

The factory-installed 1/2×28 threaded barrel opens the door to suppressor use and compensators, allowing users to customize the system for stealth, reduced recoil, or enhanced velocity. Thread protectors are included, ensuring durability when the muzzle is unadorned.

---

X-RAY3 Day/Night Sights & Optics-Ready Slide

Visibility is never compromised. The tritium-powered X-RAY3 sights offer exceptional target acquisition in both daylight and low-light environments. For red dot users, the optics-ready slide accommodates the ROMEO1PRO, Deltapoint Pro, and other popular miniature reflex optics via adapter plates—making this one of the most versatile carry pistols available.

---

Advanced Legion Finish & Branding

The signature Legion Gray PVD finish is more than just aesthetics. It provides enhanced corrosion resistance, surface hardness, and reduced friction—ideal for concealed carry, competition, or duty use. The Legion logo embedded into the slide and grip panel adds exclusivity and elite-tier appeal.

---

Performance on the Range

The SIG P320 X CARRY LEGION offers tight groupings, fast splits, and excellent shot recovery. With its added mass and low bore axis, the pistol demonstrates minimal muzzle flip even with rapid double taps or controlled pairs.

In head-to-head trials with other compact tactical pistols, including the Glock 19 MOS, CZ P-10C, and Walther PDP Compact, the X CARRY LEGION routinely outperformed competitors in recoil management, accuracy, and trigger quality.

Whether running drills, shooting from barricades, or engaging steel at distance, users report improved consistency and confidence with the X CARRY LEGION in hand.

---

Modular Fire Control Unit (FCU)

As with all SIG P320s, the removable FCU (fire control unit) makes the LEGION one of the most modular striker-fired pistols on the market. Users can transfer the serialized FCU into different grip modules or slide configurations—going from compact to full size in minutes, without the need for an FFL transfer.

---

• No Manual Safety: The X CARRY LEGION utilizes SIG’s internal safety systems, including striker and disconnect safeties, and a drop-safe design.

• Proven Duty Reliability: The P320 platform has been adopted by the U.S. military and several global law enforcement agencies, ensuring battlefield-tested reliability and durability under extreme conditions.
