True Prec Bbl Sig P365 Fuse Blk Dlc

The True Precision barrel for Sig Sauer P365-FUSE is a drop-in upgrade designed for shooters who want tighter groups and better reliability from their compact 9mm. Built to tighter tolerances than factory Sig barrels, this USA-made component swaps directly into 4.3" P365-FUSE models without gunsmithing. True Precision barrels are engineered around precision: proprietary broach-cut rifling, optimized chamber and feed ramp geometry, and stainless steel that's sourced and inspected to exacting standards.

If you carry a P365-FUSE or run it for defensive training, a quality aftermarket barrel pays dividends in shot consistency and ammunition compatibility. True Precision's approach emphasizes feeding everything—factory rounds, budget ammunition, even cast lead loads—without the feeding hiccups that plague some OEM designs. The 1/10" right-hand twist and 6-groove rifling profile are tuned for reliable expansion and performance across the velocity spread you'll encounter in carry and training ammo.

This is the black DLC (Diamond-Like Carbon) finish version, a coating that resists corrosion and reduces friction. Drop it in, function-test, and you're ready to shoot. True Precision barrels appeal to competitive shooters, defensive-minded carriers, and anyone who refuses to accept mediocre precision from a gun small enough to pocket.
