The True Precision Match Barrel (brand part no. TP-P365B-X) is a 9mm, 3.10-inch drop-in barrel machined from 416R stainless steel and built specifically for the Sig Sauer P365. True Precision cuts advanced chamfers and a refined feed ramp designed to outperform the factory OEM barrel, helping ensure reliable feeding across a wide range of ammunition types. The barrel’s proprietary stainless steel broach-cut rifling underscores the fit and finish shooters expect from a dedicated P365 upgrade, and it also fits the SAS, X, Spectre Comp, and XMACRO Comp variants.
