This True Precision barrel (brand part number TP-P365B-XG) is a drop-in match-grade upgrade for the Sig Sauer P365, machined from 416R stainless steel and cut with True Precision’s proprietary broach-cut rifling for accuracy that outperforms the factory barrel. It’s designed for the 3.1-inch P365, SAS, X, Spectre Comp, and X-MACRO Comp 9mm models, with advanced cuts, chamfers, and an improved feed ramp geometry built in to ensure reliable feeding across ammunition types. This non-threaded version keeps the factory profile for owners who don’t need a muzzle device.
