The True Precision 9MM Stainless Threaded Barrel for Sig P320 Compact is a precision-engineered drop-in replacement built for shooters who demand accuracy and reliability. Machined from 416R stainless steel sourced and manufactured entirely in the USA, this threaded barrel transforms your P320 Compact into a suppressor-ready platform while maintaining full compatibility with your existing firearm. The 4.64" barrel length (measured from breechface to muzzle) delivers the balanced handling of the Compact platform with the advantage of 1/2x28 threads ready for your can or compensator.

What sets this barrel apart is its proprietary broach cut design—an advanced rifling geometry specifically engineered to improve accuracy potential without sacrificing versatility. The 6-groove rifling and 1/10 RH twist will reliably digest any 9mm ammunition you feed it, including cast lead rounds, giving you real flexibility at the range or in the field. An 11-degree competition-style target crown ensures consistent velocity and tighter groupings. The included Viton high-heat integral O-ring lock thread protector keeps your threads protected when you're not running a suppressor, and the protector design handles sustained use without degradation.

This isn't a generic barrel—it's been refined beyond OEM specs with improved chamfers, radius cuts, and a better overall fit inside the slide. The barrel retains the loaded chamber indicator cut, so it'll interchange smoothly with your other P320 variants. Installation is straightforward as a drop-in replacement, though minor fitting may be needed on some X-Carry models. Whether you're building a suppressed duty rig, a dedicated match pistol, or simply upgrading your Compact's accuracy, this American-made barrel delivers the precision and durability that serious shooters expect.
