Description
The Sig Sauer P320 XCarry Legion 9mm 4.6” Threaded is a purpose-built carry pistol that delivers duty-grade reliability with competition-inspired accuracy. Built around the proven P320 platform, this model combines a TXG tungsten-infused grip module for reduced muzzle flip with a factory-threaded barrel for suppressor or compensator use. You get XRAY3 day/night sights, an optic-ready slide, and a skeletonized flat trigger—all in a package designed for shooters who demand precision under pressure.

Key Features
- TXG Tungsten-Infused Grip Module – Lowers the pistol’s center of gravity to reduce felt recoil and keep your sight picture flat during rapid strings. This matters because a heavier, more stable grip translates directly into faster follow-up shots and tighter groups.
- 4.6-Inch Threaded Barrel (1/2×28) – Factory-threaded for suppressors, compensators, or muzzle brakes without aftermarket work. It matters because you can run a suppressor for reduced noise or a compensator for even less muzzle rise, all while maintaining OEM reliability.
- XRAY3 Day/Night Sights – Tritium inserts with bright front ring for low-light acquisition and steel rear for durability. This matters because you get a consistent sight picture from bright sun to total darkness without changing batteries or swapping sights.
- Optic-Ready Slide – Milled for direct mounting of popular micro red-dots (including SIG ROMEO1Pro, Leupold DeltaPoint Pro, and Trijicon RMR with adapter plate). It matters because you can add a red dot without sending the slide to a machine shop, keeping the gun in service.
- Skeletonized Flat Trigger – Reduces trigger travel and provides a crisp, consistent break at approximately 4.5 lbs (per Sig Sauer specs). It matters because a predictable trigger press improves accuracy and helps new shooters avoid flinching.
Who It’s For
This pistol is for the shooter who wants a carry-size gun that doesn’t compromise on performance. If you’re a training student looking to move from a standard compact to a more capable platform, or a new shooter ready to invest in a firearm that will grow with your skills, the XCarry Legion fits. It bridges the gap between a daily concealed carry piece and a range-ready competition gun—no trade-offs needed.
Pros & Cons
- Pro: TXG grip dramatically reduces perceived recoil for a 9mm of this size.
- Pro: Threaded barrel is ready for suppressors right out of the box.
- Con: The tungsten-infused grip adds weight (29.6 oz unloaded) compared to standard P320 carry models—something to consider if you prioritize absolute lightness for all-day carry.

FAQ
What magazines does the Sig Sauer P320 XCarry Legion use?
It uses standard P320 17-round magazines. The pistol ships with one flush-fit 17-round mag. Extended magazines (21-round) are also compatible.
Can I mount a Trijicon RMR directly to the slide?
The slide is cut for SIG ROMEO1Pro and Leupold DeltaPoint Pro directly. For a Trijicon RMR, you’ll need the SIG SAUER RMR adapter plate (sold separately).
Is the threaded barrel suppressor-ready?
Yes. It has a 1/2×28 thread pitch, which is the industry standard for 9mm suppressors and compensators. No adapter needed.
What holsters fit this pistol?
Holsters designed for the P320 XCarry (with TXG grip) work. The threaded barrel may require a holster with an open muzzle end. Check with manufacturers like Safariland, Tier 1 Concealed, or Vedder for specific fit.
