The True Precision Duty Series Threaded Barrel for Sig Sauer P365 is a drop-in ready 9mm upgrade designed for the 3.1" P365, P365 SAS, and P365X (3.1") models. Built from USA-sourced certified 416R stainless steel, this 3.75" overall threaded barrel is engineered in America to the same exacting tolerances as other TRUE barrels, without extra cosmetic features such as flutes or a top logo.
Proprietary stainless steel broach-cut, 6-groove rifling with a 9mm 1:10 RH twist and a SAAMI spec 9x19 Luger chamber support accuracy and consistency. Improved fit from OEM includes added chamfers, radius cuts, and a re-engineered feed ramp for more reliable function with defensive ammo versus the original Sig design. This barrel does not retain the LCI cut-out. 1/2x28 muzzle threads include a high-heat integral O-ring lock thread protector. Built for reliable everyday carry performance and backed by a performance and function warranty.
