Availability: In Stock
The True Precision Gold Titanium Nitride threaded barrel for Sig P320 Compact is a precision-engineered drop-in replacement that brings competition-grade accuracy and durability to your carry or range setup. Manufactured entirely in the USA from 416R stainless steel, this barrel is built to tighter tolerances than factory Sig barrels, with proprietary broach-cut rifling specifically designed to enhance accuracy potential while remaining safe for all ammunition types—including cast lead rounds. If you're running a P320 Compact, X-Carry, or M18, this threaded barrel offers the performance upgrade serious shooters demand without complicated installation.
The 1/10 RH twist rifling and competition-style 11-degree target crown work together to support precision shooting, whether you're fine-tuning at the range or relying on your pistol in the field. The threaded muzzle comes equipped with a Viton high-heat integral O-ring lock thread protector, so you're ready to mount a suppressor or accessory immediately—no separate parts to chase down. The barrel measures 4.64 inches from breechface to muzzle without the protector, fitting within the compact footprint of your platform. True Precision refined the chamber to SAAMI spec and added enhanced chamfers and radius cuts throughout, resulting in a noticeably better-than-factory fit that cycles reliably across different P320 variants. The Gold Titanium Nitride finish delivers corrosion resistance and a distinctive look while holding up to the wear of regular shooting.
Installation is straightforward—this is a genuine drop-in design with no gunsmithing required on Compact models (minor fitting may be necessary on some X-Carry variants, and note that this barrel does not fit the X-Compact). If you own multiple P320 frames, the barrel retains the M18 loaded chamber indicator cut, preserving cross-platform compatibility. For shooters looking to upgrade their P320 Compact's accuracy, durability, and threaded versatility without compromising reliability, this barrel delivers.
