True Precision Barrel Features The True Precision Barrel is machined from USA-sourced certified 416R stainless steel a material prized for its strength and corrosion resistance in demanding defensive and range use. A proprietary broach-cut six-groove rifling pattern with a 1:10 twist stabilizes a wide range of 9mm bullet weights including cast lead projectiles that some factory barrels are not optimized for. The barrel measures 4 overall and is machined to a SAAMI spec 9x19 Luger chamber for consistent reliable ignition. This non-threaded configuration keeps the barrel s profile clean for shooters who do not need a threaded muzzle. An improved and widened feed ramp cut wider than the OEM Ruger RXM ramp provides more reliable feeding of hollow point and defensive ammunition a meaningful upgrade for anyone carrying the pistol for personal protection. The Gold TiN finish adds a distinctive eye-catching look while providing additional wear resistance over bare stainless steel. As a match grade drop-in barrel it is designed to install without gunsmithing or fitting work giving RXM owners a straightforward accuracy and reliability upgrade. This barrel is a direct fit for shooters who want to personalize and improve their Ruger RXM s performance.
