True Precision SIG P365XL 9mm Luger 3.70" Threaded Black Nitride Drop-In Barrel

Upgrade or refresh the slide internals of your SIG Sauer P365XL platform with the True Precision SIG P365XL drop-in pistol barrel, chambered in 9mm Luger and engineered specifically for the 3.7" P365XL, P365X-MACRO, and P365XL Tacops pistols.

This threaded barrel is precision-machined from certified 416R stainless steel and finished in a low-friction, wear-resistant Black Nitride coating. The 3.70" length matches the original factory P365XL profile, and the broach-cut rifling uses a 1:10" right-hand twist for consistent, stable bullet engagement with standard 9mm loads.

A precision 1/2x28 thread pattern at the muzzle accepts compensators, suppressors, and other compatible muzzle devices, while the drop-in design installs directly into the factory slide without gunsmithing. The barrel ships with no factory sights installed, leaving the slide's optic-ready configuration undisturbed.

Designed, machined, and quality-inspected in the USA, this True Precision barrel is a straightforward, premium aftermarket option for P365XL-platform owners looking to add threading for a muzzle device or simply upgrade from the factory barrel.
