The TRUE Duty Barrel for Sig Sauer P365 XL, a standard in precision engineering for shooters who want performance without extra cosmetic features. Designed for the 3.7″ P365XL, XMACRO, and TACOPS 9mm models (with a 3.1″ P365 version also available), this American-engineered barrel is built to the same exacting tolerances as all TRUE barrels but omits flutes and a top logo for a clean, duty-focused look. The TRUE Duty series is purpose-built for everyday carry, featuring their proprietary stainless steel broach-cut rifling for unmatched accuracy, an improved feed ramp to help ensure reliable feeding with a wide range of ammunition designs, and their most durable black nitride coating for long-term protection. This true drop-in upgrade is crafted to meet the demands of serious users; experience the American-made precision and performance that only TRUE delivers.
