The True Precision P365 9mm copper threaded barrel is a drop-in replacement for your Sig Sauer P365 that combines tighter tolerances, refined geometry, and 1/2 x 28 muzzle threading—all in a 416R stainless steel package built for accuracy and reliability. Whether you're running this compact daily carrier with defensive ammo or fine-tuning it for the range, this barrel steps up from factory specs in ways that matter: improved chamber design, refined feed ramp geometry, and aggressive chamfering that cycles defensive ammunition more reliably than stock.
The 1/2 x 28 threads let you run suppressors, compensators, or specialized muzzle devices, opening up options for sound reduction, recoil management, or backup sighting. The 1/10 right-hand twist is optimized for 9mm Luger and fires to SAAMI spec, so you can trust it with any commercial load. Because a tighter barrel yields better mechanical accuracy in a pistol, the precision fit of this replacement makes a real difference when you're testing your marksmanship or relying on your carry gun for serious use.
Installation is straightforward—it's designed as a drop-in unit for your P365, so no gunsmithing required. The copper finish provides both visual appeal and practical corrosion resistance in a working gun. If you've been thinking about upgrading your P365's trigger control and accuracy potential without replacing the whole pistol, this barrel is the no-fuss way to do it.

Yes. The barrel is SAAMI spec and designed for all commercial 9mm Luger loads, including defensive ammunition.
The precision fit creates tighter lockup between the barrel and slide compared to factory tolerances. A tighter fit reduces play and improves mechanical accuracy. Additionally, the refined feed ramp and chamber geometry contribute to more reliable feeding and consistent performance.
