Sig Sauer P320 X-Five Legion 9mm 5″ TXG XGrip 3x10rd
Pros & cons
What works
- Weighs 43.5 oz unloaded — the TXG grip adds 13.4 oz of stabilizing mass over a standard polymer P320 frame.
- Includes an optic-ready slide cut for a Leupold DeltaPoint Pro, saving ~$200 in gunsmithing/milling costs.
- 5-inch match-grade barrel provides a 12.75-inch sight radius for precise shot placement at 25+ yards.
- Stainless steel frame and LEGION Gray Cerakote resist holster wear significantly better than standard nitron finishes.
Trade-offs
- Manual safety adds an unnecessary failure point and training complication for a dedicated competition gun.
- Does NOT include three magazines as the base model does; restricted-state versions ship with one 10-round magazine only.
- LEGION Gray finish shows carbon fouling and brass marks more readily than a standard black nitron finish.
- At $1038.99 MSRP, it requires an additional $300-$600 optic investment to be functional for its primary purpose.

About this product
The Sig Sauer P320 X-Five Legion is a full-size competition pistol engineered for superior balance and rapid split times through a weighted tungsten-infused TXG XGrip module and a 5-inch match-grade barrel. It's a purpose-built platform for USPSA Carry Optics or Steel Challenge competition, but its 43.5-ounce weight and manual safety make it overly specialized for daily concealed carry. Sig's LEGION lineup represents their top-tier performance category, and this model delivers on that promise with immediate optic-mounting capability right from the box.
What is the Sig Sauer P320 X-Five Legion 9mm used for?
This pistol is engineered for sanctioned, high-speed accuracy competition like USPSA Carry Optics division or Steel Challenge, not for duty carry or home defense. The 43.5-ounce unloaded weight, achieved via the tungsten-infused TXG XGrip, dampens muzzle rise dramatically compared to a standard polymer-frame pistol, allowing for faster perceived recoil recovery and tighter shot groups on partial targets at 25 yards. Its 5-inch barrel provides a 12.75-inch sight radius with the included fiber-optic/adjustable rear sight combo, shaving tenths of a second off transition times compared to a hunting rifle like the Stevens 334 where speed is secondary to precision.
How does the Sig Sauer P320 X-Five Legion compare to the SIG P320 X-Compact?
The X-Five Legion is superior for deliberate, repeatable competition shooting, while the X-Compact is better for all-day, concealed personal defense. The critical difference is 13.4 ounces of mass: the Legion's TXG grip module pushes the unloaded weight to 43.5 ounces, sacrificing daily carry comfort for a 40% reduction in muzzle flip during rapid-fire drills. The X-Compact uses a standard polymer grip and a 3.6-inch barrel, making it nearly an inch and a half shorter in overall length and significantly easier to conceal, but it will not offer the same level of inherent stability for follow-up shots on the clock.
What does it weigh and what are the dimensions?
Unloaded, the pistol weighs 43.5 ounces (2.72 lbs) with an overall length of 8.5 inches and a height of 5.9 inches to the top of the rear sight. The key dimension is the 5-inch cold hammer-forged barrel, which yields a 12.75-inch sight radius critical for precise alignment during timed stages. With three loaded 10-round magazines adding approximately 18 ounces, the operational weight for a loaded start in a competition stage jumps to over 61 ounces, a mass you'll feel immediately when transitioning from a lighter platform like a Stevens 555 shotgun.
Who is this NOT for?
This pistol is not for a first-time gun owner, a concealed carry permit holder seeking a daily driver, or anyone on a strict budget for a multi-role firearm. The manual safety, while appreciated by some competitors, adds an unnecessary failure point and training hurdle for defensive shooting where simplicity under stress is paramount. The $1,038.99 MSRP does not include an optic, which is mandatory to be competitive in its intended division, adding another $300-$600 to the initial investment before even a single round of 9mm is purchased.
What's in the box?
You receive the optic-ready slide and TXG frame assembly, a single 10-round magazine, a plastic carrying case, a cable lock, and the owner's manual—not the three magazines as sometimes advertised for non-restricted states. Confirming the exact magazine count with your dealer before purchase is crucial for compliance; some distributors ship only one 10-round magazine to restricted jurisdictions. The slide is pre-milled for a DeltaPoint Pro footprint, but you must source and torque the mounting screws and optic separately, a 15-minute gunsmithing task.
Is the Sig Sauer P320 X-Five Legion worth it at $1038.99?
At this price point, it is worth the investment only if you are actively competing in optics-based pistol sports and require the specific mechanical advantages of its weighted frame. The value is in its out-of-the-box readiness for a Carry Optics rig, as the TXG module and optic cut would cost nearly $400 to add to a standard P320, not including gunsmithing. For a recreational shooter or someone whose primary need is home defense, a standard P320 or a more versatile platform offers 90% of the performance for 60% of the cost, making the Legion's premium hard to justify.

Frequently asked questions
- Is it compatible with standard P320 magazines?
- Yes, it accepts any standard SIG Sauer P320 full-size 9mm magazine. However, for competition use in capacity-restricted divisions, you must use the included 10-round magazines or source aftermarket basepads to limit higher-capacity mags. The TXG grip module uses the same magazine well dimensions as other full-size P320 frames.
- Does this work with a Holosun 507C optic?
- No, not directly. The slide is milled specifically for the Leupold DeltaPoint Pro footprint, which has a unique screw pattern and recoil lug system. Mounting a Holosun 507C requires a third-party adapter plate from CHPWS or C&H Precision, adding approximately 0.15 inches of height over bore and costing an additional $50-$70.
- Can the manual safety be deleted?
- Functionally, yes, but not without significant modification. The TXG grip module is molded with a cavity for the safety lever, and the FCU (Fire Control Unit) is safety-equipped. To delete it, you must purchase a non-safety FCU from SIG (~$350) and fill the grip cavity with an epoxy like Acraglas, a 2-hour process best left to a qualified gunsmith.
- How long does shipping to an FFL take?
- For in-stock items, Ironclad Armory processes and ships within 1-2 business days via UPS Ground. Transit time to most FFLs in the continental US is 3-7 business days. You must have your chosen FFL's license on file with us before the order ships; failure to provide this adds 24-48 hours to processing.
- Does it come with suppressor-height sights?
- No. It ships with a Dawson Precision fiber-optic front sight and an adjustable black rear sight, which are standard height. These will not co-witness with most common pistol red dot optics. If you plan to run a suppressor or require a co-witnessing iron sight backup, you'll need to purchase taller sights separately for approximately $80-$120.
