The True Precision Barrel for the SIG Sauer P365XL (brand part no. TPP365XLBXBL) is a drop-in ready, 9mm replacement barrel machined from 416R stainless steel and sized for the 3.7-inch P365XL, X-MACRO, and TacOps models. True Precision builds its barrels around advanced cuts, chamfers, and a feed ramp designed to outperform OEM standards, aiming for reliable feeding across a wider range of ammunition, including defensive loads that can be pickier in a factory barrel. A 1:10 right-hand twist rate rounds out a barrel built to tighten group sizes without changing anything about the pistol’s factory fit.
