True Precision Barrel for Ruger RXM Features The True Precision barrel for the Ruger RXM is built around a proprietary broach cut 6-groove rifling pattern with a 1:10 right hand twist that stabilizes everything from lightweight training loads to cast lead ammunition. The SAAMI spec 9x19 Luger chamber is cut to tight tolerances for improved accuracy over the factory barrel while an 11 degree target crown protects the muzzle from wear and helps consistent bullet exit. An improved and widened feed ramp over OEM increases reliability when running hollow point and other defensive ammunition profiles. This match grade drop-in design lets shooters upgrade their RXM without any fitting or gunsmithing. Machined from USA-sourced 416R stainless steel billet the barrel offers excellent corrosion resistance and long-term durability under sustained use. The black nitride finish adds a further layer of protection while keeping the barrel s proprietary threading ready for a 1/2x28 muzzle device. At 4.5 inches overall the threaded barrel is a direct fit for 3.9 RXM 9mm models replacing the factory barrel without frame modification. For RXM owners chasing tighter groups and more reliable feeding this True Precision barrel is a straightforward American-made upgrade.
