Faxon Firearms Match Series Barrel Features The Faxon Firearms Match Series Barrel is machined in-house from 416-R stainless steel with better-than-factory tolerances that deliver a consistent tighter lockup than the stock Sig Sauer P365 barrel. Conventional rifling at a 1:10 twist stabilizes a broad range of 9mm projectiles from standard defensive loads to cast lead bullets that many factory barrels cannot run reliably. Fluting along the barrel reduces reciprocating mass and adds a distinctive look while keeping the barrel structurally rigid for accuracy under repeated firing. The barrel drops directly into factory-spec P365 slides with no gunsmithing required making installation straightforward. A black Nitride or PVD coating increases surface lubricity and hardness extending service life and improving resistance to corrosion and everyday wear from carry and range use. The half inch by 28 threaded muzzle accepts a suppressor comp or thread protector for shooters who want a quieter or more controllable P365. This combination of match-grade tolerances and a durable finish makes the barrel a strong choice for concealed carry shooters who still want improved accuracy potential. It is a genuine performance upgrade over the factory barrel for anyone building out their P365.
