Drop-in threaded 9mm barrel for the Ruger RXM 3.9" 9mm pistol. True Precision machines this barrel from 416R stainless steel and finishes it in a black nitride (QPQ) coating for corrosion resistance and a deep matte appearance. The 1/2x28 muzzle threads accept 9mm compensators, flash hiders, and suppressors.
Fit: Ruger RXM 9mm (3.9" standard models). True Precision's proprietary broach-cut rifling combined with their SAAMI-spec chamber outperforms OEM accuracy 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 current recoil spring weight after the swap.
