The True Precision drop-in barrel for the Ruger RXM is built for the 3.9-inch 9mm RXM platform. Copper PVD finish over 416R stainless steel, with broach-cut rifling tuned for tight groups across hollow-point, lead, and full-jacketed loads. Engineered, machined, and finished in Georgia, USA. True Precision's advanced feed-ramp geometry and chamber chamfer outperform OEM standards and feed reliably across modern defensive ammunition. Features: Fits Ruger RXM 9mm (3.9 in barrel length) Copper PVD finish over stainless steel Broach-cut rifling for accuracy and consistent feed Drop-in replacement - no fitting required Compatible with factory RXM recoil assembly Made in USA Drop-in installation: remove the factory barrel, swap in the True Precision unit with the OEM recoil assembly, and function-check. Brief break-in (~50 rounds) is recommended to fully seat the rifling and confirm reliable feeding with your chosen defensive load. Finish note: The copper PVD coating will show wear at metal-to-metal contact points - primarily the locking lug face and barrel hood - over time. This is normal and does not affect function or accuracy.
