Key Features
- TXG Tungsten-Infused Grip Module – Adds significant weight to the grip, lowering the bore axis and reducing perceived recoil. This means steadier aim for new shooters and faster recovery for everyone.
- XSeries Flat Skeleton Trigger – Provides a crisp, consistent break with a short reset. The flat face helps keep your finger straight, improving accuracy under pressure.
- 4.6″ Threaded Barrel (1/2×28) – Ready for suppressors or compensators out of the box. The extra length also boosts muzzle velocity slightly.
- Optic-Ready Slide with Adjustable XRAY3 Sights – Cut for popular red dots (RMSc footprint) and includes suppressor-height iron sights that co-witness with most optics. Great for shooters transitioning to dot sights.
- Legion Gray Cerakote Finish – Durable, corrosion-resistant coating that holds up to daily carry and range use. The distinctive color makes it easy to spot in a safe or range bag.
Who It’s For
This pistol is ideal for family shooting coaches teaching new shooters, because the reduced recoil and flat trigger build confidence quickly. It also suits experienced shooters who want a carry-size gun that performs like a competition piece. If you’re looking for a do-it-all 9mm that can run suppressed or with a dot, this Legion delivers.
Pros / Cons
- Pro: Outstanding recoil management thanks to the TXG grip module.
- Pro: Factory optic-ready with quality night sights—no extra machining needed.
- Pro: Threaded barrel included, saving you $150+ on aftermarket parts.
- Con: The Legion Gray finish requires occasional cleaning to maintain appearance—it’s not a hard-use duty finish like some military-grade coatings. A minor trade-off for the aesthetic.

FAQ
Is the Sig Sauer P320 XCarry Legion 9mm 4.6″ threaded, 17rd compatible with my existing P320 holster?
Most P320 holsters will fit, but the threaded barrel and optic cut may require an open-end or optic-ready holster. Always verify with your holster manufacturer before purchase.
What optics fit the P320 XCarry Legion slide?
The slide is cut for the RMSc footprint, so it accepts popular micro red dots like the Holosun 507K, Sig Romeo Zero, and Shield RMSc. Larger optics like the Trijicon RMR will need an adapter plate.
Can I use standard P320 magazines with this gun?
Yes. The XCarry Legion uses standard P320 17-round magazines. It also accepts 21-round extended magazines for range use or competition.
Does this pistol come with a suppressor?
No. The threaded barrel is suppressor-ready, but the suppressor must be purchased separately. The 1/2×28 thread pattern is the most common for 9mm suppressors.
According to a 2025 NSSF survey, the P320 platform now accounts for over 15% of all striker-fired pistol sales in the U.S. – a testament to its reliability and versatility.
