True Prec Bbl Sig P365 Fuse Cpr

The True Precision barrel for Sig Sauer P365-FUSE is a drop-in replacement designed to elevate accuracy and reliability in your compact 9mm. Built from USA-sourced certified 416R stainless steel with proprietary broach-cut rifling, this barrel brings match-grade performance to a platform trusted for everyday carry and sport shooting. It's compatible with the 4.3" P365-FUSE 9mm and engineered to feed any ammunition type reliably—including cast lead rounds—without the factory's LCI (loaded chamber indicator) cutout found on OEM barrels.

True Precision barrels are known for going beyond stock specifications. The advanced chamber geometry and optimized feed ramp deliver consistent, dependable cycling across the full spectrum of 9mm loads, from budget practice ammo to premium defensive rounds. If you've ever felt your factory barrel was the limiting factor in your P365-FUSE's accuracy potential, this is the upgrade that matters: it's a straightforward swap that tightens groups and builds confidence in a platform that's already punched above its weight.

The 6-groove, 1/10 right-hand twist rifling is cut to True Precision's specifications and promises the durability and accuracy associated with broach-cut barrels. For shooters who demand tighter tolerances and consistent performance—whether you're at the range refining your fundamentals or relying on your P365-FUSE for personal protection—this barrel removes guesswork from the equation.
