True Precision Barrel for Sig Sauer P320 X-Compact Features The True Precision barrel drops directly into the Sig Sauer P320 X-Compact offering an easy drop-in upgrade over the factory barrel. Machined from 416R stainless steel sourced and manufactured entirely in the USA the 4.3 barrel uses an advanced proprietary broach cut design engineered specifically for increased accuracy potential. Its 6 groove rifling with a 1:10 RH twist is safe for all ammunition types including cast lead giving reloaders and budget-conscious shooters more flexibility. A satin stainless finish gives the barrel a clean corrosion resistant appearance. This threaded version features a 1/2x28 thread pattern with an included Viton high heat integral O-ring lock thread protector keeping the muzzle protected when not running a compensator or suppressor. The barrel uses a SAAMI spec chamber for reliable consistent feeding and extraction. An improved and widened feed ramp over the factory design supports more reliable feeding of hollow point and defensive ammunition. These refinements including added chamfers and improved radius cuts give the True Precision barrel a better than OEM fit and function for the P320 X-Compact.
