True Precision P320 X-Compact 9mm Threaded Barrel

The True Precision P320 X-Compact 9mm threaded barrel is a direct-fit replacement barrel designed for SIG Sauer P320 X-Compact pistols. If you're running a suppressor on your compact carry or range gun, or just want the option to thread one on later, this barrel swaps in without gunsmithing—a straightforward upgrade for shooters who want suppressor-ready capability on a tight platform.

True Precision barrels are known for precision machining and clean fitment. This one comes finished in titanium nitride (TiN), a hard PVD coating that resists corrosion and wear while adding a distinctive gold-colored appearance. The 1/2x28 thread pattern is the standard for 9mm suppressors, so you'll have no shortage of silencer options. Whether you're building a soft-shooting home-defense gun, setting up for subsonic practice, or just future-proofing your X-Compact, a quality threaded barrel is a low-commitment way to unlock that flexibility.

Installation is straightforward for anyone comfortable with basic P320 takedown. The barrel is engineered to OEM tolerances, so you can expect the same reliability and accuracy you get from factory Sig hardware—just with the added utility of a threaded muzzle and the durability of a titanium nitride finish.

Frequently Asked Questions

Will this barrel fit my P320 X-Compact?

Yes—this barrel is engineered specifically for the SIG Sauer P320 X-Compact. It's a direct fit and requires no modification.

What suppressors will work with this barrel?

The 1/2x28 thread pattern is the standard for 9mm suppressors. Any suppressor rated for that thread pitch and caliber will mount directly.

Do I need a gunsmith to install this?

No. P320 barrel replacement is part of standard field-stripping and can be done by anyone comfortable with basic pistol takedown. If you're unsure, a gunsmith can handle it quickly.

Why titanium nitride finish?

The TiN coating is harder and more corrosion-resistant than plain steel, extending the life of the barrel—especially useful if you're suppressed shooting or exposing it to moisture regularly. It also adds visual distinction with its gold color.
