True Precision Duty Barrel Features The True Precision Duty Barrel is purpose built for the 3.1 Sig Sauer P365 P365 SAS and P365X pistols using proprietary broach cut rifling across six grooves with a 1:10 right hand twist suitable for jacketed and cast lead ammunition alike. Machined from USA sourced certified 416R stainless steel the barrel meets SAAMI spec for 9x19 Luger and is finished in black DLC for added corrosion resistance. The 1/2x28 threaded muzzle includes a high heat integral o-ring lock thread protector keeping the threads protected until the owner is ready to mount a compensator or suppressor. An improved fit over the factory original barrel comes from added chamfers radius cuts and a re-engineered feedramp. These upgrades allow more reliable function with defensive hollow point ammunition than the original Sig Sauer design offers an important improvement for a daily carry pistol. The barrel does not retain the loaded chamber indicator cutout found on the factory barrel giving it a clean blank hood with no fluting or pocketed face. At 3.75 inches overall with a 3.1 inch chambered length it is a drop in fit for the compact P365 platform. The True Precision Duty Barrel is a reliable upgrade for sale at GrabAGun for P365 owners seeking improved accuracy and threaded barrel versatility.
