True Precision True Duty Series Sig P365 XL 3.7" Threaded Barrel – Black Nitride
The True Precision True Duty Series Threaded Barrel (TP-P365XLDB-XTBL) is a match-grade, drop-in performance upgrade designed specifically for the Sig Sauer P365 XL, X-Macro, and Tacops 9mm models. The "True Duty" series is engineered to provide the same extreme precision and tight tolerances as True Precision’s premium fluted barrels but with a clean, no-frills aesthetic optimized for professional use and everyday carry. By utilizing a smooth, non-fluted exterior, True Precision offers a streamlined barrel that focuses entirely on accuracy, reliability, and value.
Machined from USA-sourced certified 416R stainless steel, this barrel features proprietary broach-cut 6-groove rifling, which allows for a broader range of ammunition types, including cast lead. The feed ramp has been re-engineered and high-polish finished to outperform OEM standards, ensuring smoother feeding with high-performance defensive hollow points. Finished in a rugged Black Nitride (Melonite) coating, this barrel is highly resistant to wear and corrosion. With a 1/2x28 thread pitch, it comes ready to accept compensators or suppressors and includes a high-heat Viton O-ring thread protector to ensure the cap stays secure during fire.
Note: Fits P365 XL, X-Macro, and Tacops (3.7" slides). It is NOT compatible with the X-Macro Comp or Spectre Comp ported slides which utilize the shorter 3.1" barrel. This model does NOT retain the Loaded Chamber Indicator (LCI) cut-out, which helps keep your optics cleaner by reducing gas blowback.
Key Features
- Match-Grade Performance: Proprietary broach-cut rifling provides superior consistency and accuracy over standard factory barrels.
