Zaffiri Precision Barrel Features The Zaffiri Precision Barrel is precision manufactured in the USA to the highest standards providing exceptional accuracy over a factory stock barrel in the Sig Sauer P365. Conventional rifling combined with a polished chamber and bore lets this barrel perform well across lead plated and jacketed bullet types giving the shooter flexibility in ammunition selection without a drop in reliability. Finished in a matching stainless steel exterior the barrel is a drop in design meaning it is ready to use as a perfect replacement for the existing Sig barrel with no additional fitting required. A 1:10 twist rate and six grooves match the specifications that make the P365 platform shoot consistently well. A 1/2x28 threaded muzzle opens the door to compensators and suppressors on a pistol that ships from the factory without a threaded option in most configurations and a thread protector is included to keep the threads clean when no device is installed. At 6 ounces the barrel adds no meaningful weight to the compact P365 frame. High quality performance is the stated goal behind this barrel and the stainless steel construction is built to hold up to the wear of regular range use and daily carry. This Zaffiri Precision Barrel is available for sale at GrabAGun for Sig Sauer P365 owners who want a precision made threaded replacement barrel.
