Brownells Sig Sauer P365 Barrel Features This Brownells barrel is machined from 416R stainless steel that is hardened and cut to precise dimensions giving the Sig Sauer P365 a tighter lockup than the stock barrel provides. That tighter fit reduces the small amount of slop that limits accuracy in a factory pistol so shots land closer together at speed and at distance alike. The button rifled bore carries a standard 1 in 10 inch right hand 6 groove twist that stabilizes a wide range of 9mm Luger factory loads. Every barrel is laser engraved with its chambering and the specific Sig model it fits so there is never any doubt about compatibility once it is out of the package. The threaded muzzle uses a 1/2x28 thread pitch opening the door to mounting a compensator to tame recoil or a sound suppressor for hearing protection and reduced signature. An extra hard Black Nitride finish coats the stainless steel to resist surface wear from repeated cycling while also standing up to the corrosion that range use and daily carry both invite. Installation is a straight drop in swap on most P365 pistols requiring no fitting or gunsmith work to get back up and running. For a concealed carry pistol asked to perform reliably this barrel is a straightforward upgrade path to real accuracy gains.
