True Precision TPP365BXG Sig P365 9mm Luger 3.10" Gold TiN Stainless Drop-In Barrel

The True Precision TPP365BXG is a drop-in aftermarket pistol barrel for the Sig Sauer P365 family, chambered in 9mm Luger. Machined from 416R stainless steel and finished in a durable Gold TiN coating, this 3.10" match-grade barrel installs directly into the slide without fitting and is engineered as a true drop-in replacement for the Sig P365, P365 SAS, and P365-AXG Legion.

True Precision builds this barrel with X-fluting and a 1:10" RH twist to deliver match-grade accuracy and consistent performance with a wide range of 9mm loads. The Gold TiN finish provides a striking gold appearance while adding surface hardness and corrosion resistance to the stainless substrate, making it both a functional upgrade and a visual accent for your carry or range pistol. No sights are included; the barrel is intended for use with the host pistol's existing slide and sight configuration.

Designed as a direct-fit, drop-in barrel, the TPP365BXG lets P365 owners swap their factory barrel in minutes with no gunsmithing required. Whether you are running a carry P365, a P365 SAS, or a P365-AXG Legion, this True Precision barrel offers a precision-machined upgrade for your subcompact Sig.
