True Precision Sig P365XL 9mm Luger 3.70" Fluted Black Nitride Drop-In Barrel

The True Precision drop-in barrel is a precision aftermarket replacement designed specifically for the Sig Sauer P365XL and P365X-MACRO variants chambered in 9mm Luger. It installs as a direct drop-in to the factory slide, requiring no fitting or gunsmithing.

The barrel is machined from stainless steel and finished in a low-reflectivity Black Nitride coating that resists wear and corrosion while giving the pistol a distinctive custom look. Its X-fluted profile trims weight and helps clear debris between rounds, and the conventional 1:10 RH twist rate is well matched to standard 9mm bullet weights.

Measuring 3.70" overall, this non-threaded barrel keeps the P365XL's standard profile intact and ships without sights so the user can continue running the pistol's existing iron sight arrangement. It is an ideal upgrade for shooters looking to tighten groups, refresh an aging factory barrel, or simply change up the look of their carry pistol.
