SIG SAUER P320-XCARRY LEGION 9mm Threaded-Barrel Pistol

SIG SAUER P320 XCARRY LEGION 9mm

The SIG SAUER P320 XCARRY LEGION combines the adaptable P320 platform with a carry-size profile and the weight, controls, and sighting features associated with the LEGION series. This exact configuration is model 320XCA-9-LEGION-TB-R2, chambered in 9mm and supplied with a 4.6-inch threaded barrel, a Legion Gray finish, and three 17-round steel magazines. Its design is aimed at shooters who want a substantial, stable pistol without moving to a full-size grip and slide combination.

At the center of the pistol is SIG’s TXG Carry-size XGRIP module. The tungsten-infused polymer construction adds useful mass while retaining the familiar contours and modular architecture of the P320. SIG states that the pistol weighs more than 40 ounces with an unloaded magazine, helping reduce muzzle movement compared with similarly sized polymer-frame pistols. The result is a carry-size handgun that feels planted during strings of fire and gives the shooter a consistent platform for practice, competition-oriented drills, and range use.

Optic-ready slide and adjustable sights

The Legion Gray PVD-finished slide is cut for a compatible pistol optic while retaining fully adjustable XRAY3 day/night sights. SIG lists compatibility with the ROMEO1PRO, ROMEO2, DeltaPoint Pro footprint, and RMR-pattern optics when the correct mounting arrangement is used. Keeping capable iron sights on the pistol provides a complete sighting system out of the box and gives the owner flexibility when choosing whether to install an optic.

The slide’s forward and rear serrations provide grasping surfaces for routine manipulation. An extended beavertail on the grip module supports a high, secure firing grip, while the detachable extended magwell helps guide magazines during reloads. These features are integrated into the factory configuration rather than requiring the buyer to assemble a comparable setup from separate components.

Threaded barrel and tuned controls

This model uses a 4.6-inch barrel threaded 1/2×28 right hand. That thread pattern supports compatible muzzle devices and properly configured 9mm suppressor systems. Any suppressor or muzzle device should be verified for caliber, thread pitch, alignment, and pistol compatibility before use; follow the accessory maker’s installation instructions and all applicable laws.

A skeletonized flat trigger is part of the XCARRY LEGION package. SIG describes its trigger pull as up to 30 percent lighter than the standard configuration, supporting a clean, predictable press and quick reset. The pistol remains a striker-fired P320 with no external manual thumb safety on this configuration. Its controls and modular fire-control design preserve the handling approach familiar to P320 users.

Exact configuration

Who this pistol is for

The P320 XCARRY LEGION is a strong choice for shooters who prioritize controllability, a refined trigger, adaptable sighting options, and factory-ready muzzle threading in a carry-size format. The added mass is intentional: it favors stability and rapid follow-up work over minimum carry weight. Buyers looking for the lightest possible P320 may prefer a conventional polymer configuration, while those who value a flatter, more settled shooting experience will appreciate the TXG module.

Before ordering, confirm that the magazine capacity, threaded-barrel configuration, and other features are lawful in your jurisdiction. Firearms must ship to an eligible receiving FFL, and the purchaser is responsible for all required transfer procedures. Always verify the pistol is unloaded before handling, mounting an optic, installing a muzzle device, or performing maintenance, and follow the current SIG SAUER operator’s manual.
