Drop-in threaded 9mm barrel for the Ruger RXM 3.9" 9mm pistol. True Precision builds this barrel from 416R stainless steel with a hard-wearing black DLC coating that resists wear, corrosion, and carbon buildup. The 1/2x28 muzzle threads accept standard 9mm compensators, flash hiders, and suppressors.
Fit: Ruger RXM 9mm (3.9" standard models). The barrel uses True Precision's proprietary broach-cut rifling and SAAMI-spec chamber, designed to outperform OEM accuracy with mixed ammunition while feeding reliably across hollow point, FMJ, and defensive load profiles.
Run 150-200 rounds of FMJ through the new barrel to settle it before defensive carry, and verify reliable ejection with your preferred recoil spring weight after the swap.
