Product Description The True Precision True Duty Barrel for the Sig Sauer P365XL is an American-engineered, drop-in replacement barrel built to the highest tolerances for shooters who demand reliable performance from their everyday carry pistol. Designed specifically for the 3.7" P365XL, XMACRO, and TACOPS 9mm models, this barrel features True Precision&';s proprietary 416R stainless steel construction with broach-cut rifling for superior accuracy and an improved feed ramp to ensure reliable feeding across a wide variety of ammunition types. The True Duty series omits cosmetic flutes and a top logo for a clean, duty-focused profile, while still delivering the same exacting tolerances found across the full True Precision lineup. Finished in True Precision&';s most durable black nitride coating for long-lasting corrosion and wear resistance, and threaded 1/2x28 for suppressor or muzzle device compatibility, this barrel is purpose-built for serious everyday carry use and is proudly made in the USA.
