Key Features

• Tungsten-infused TXG XGrip module – Why it matters: The added mass reduces muzzle flip and felt recoil, keeping you on target for faster follow-up shots in competition or defensive drills.
• 5-inch match-grade bull barrel – Why it matters: A heavy, precision-machined barrel improves inherent accuracy and consistency shot after shot, critical for steel challenge or USPSA stages.
• Adjustable fiber-optic sights – Why it matters: The green fiber front and serrated rear allow quick sight alignment in varied lighting, while the adjustable rear lets you dial in elevation for different distances.
• Optics-ready slide – Why it matters: Accepts popular red dot footprints (RMR, DPP, Romeo) without needing custom milling, giving you the option to run a dot for faster target transitions.
• Three 17-round magazines included – Why it matters: You get enough capacity for a full match stage or extended training session without constant reloading, plus spares for the range bag.

Who It’s For

This pistol is built for competitive shooters who want a heavy, flat-shooting platform straight out of the box. It also suits serious shooters who train regularly and demand a duty-grade firearm with a tuned trigger and low bore axis. The Legion series is not a budget option; it’s for those who prioritize accuracy and recoil control over weight savings.

Pros & Cons

• Pro: The TXG grip module soaks up recoil noticeably better than standard polymer frames, giving you a significant edge in split times.
• Pro: The X-Five trigger breaks at about 4.5 lbs with a short, positive reset, making it one of the best striker-fired triggers available.
• Con: The pistol is heavy at 43.5 oz, which can be a drawback for concealed carry or all-day holster wear.
• Con: The Legion gray finish is attractive but shows wear more readily than a standard nitride finish, so plan for holster scuffs.

FAQ

Does the Sig Sauer P320 X-Five Legion come with optics mounting plates?

Yes, the X-Five Legion ships with a set of mounting plates for common reflex footprints, including RMR, DeltaPoint Pro, and Sig Romeo. You’ll need to choose the correct plate for your dot and install it per the included instructions.

What holsters fit the P320 X-Five Legion?

The X-Five Legion fits most P320 full-size holsters with a 5-inch barrel profile, but the TXG grip module is slightly wider than standard P320 frames. Many competition holsters from companies like Red Hill Tactical and Safariland offer specific Legion-fit options.

Is the P320 X-Five Legion good for concealed carry?

At 43.5 oz and a full-size frame, this pistol is not ideal for everyday concealed carry. It’s designed for competition and range use where weight and size are less of a concern.

What is the trigger pull weight on the X-Five Legion?

Per Sig Sauer specs, the X-Five trigger has a factory pull weight of approximately 4.5 lbs. The trigger features a flat face with a short, crisp break and a positive reset.

Can I use +P ammunition in the X-Five Legion?

Yes, the P320 X-Five Legion is rated for +P ammunition, but extended use of high-pressure loads may accelerate wear on the barrel and recoil spring. Standard 115-147 grain FMJ or JHP is recommended for most training and competition.
