Faxon Firearms Match Series, Button Rifled, Drop In Barrel, 9MM, 1/2X28 Thread Pitch, Fits SIG P320 Full Size, Not Compatible with M17 or X-Series Pistols, Salt Bath Nitride Finish, Black, 1:10 Barrel Twist

Faxon's match series pistol barrels for Sig P320 are machined in-house from stress-relieved 416-r stainless steel. These barrels are then given a black nitride or pvd coating to increase lubricity, barrel life, and resistance to surface wear. All barrels are conventionally rifled to allow a wider range of ammunition to be used, including cast lead. The barrels drop into factory-spec slides with no gunsmithing required. Better-than-factory tolerances ensure a consistent, tighter lockup than oem. • Handgun Type: Sig P320 Full Size • Barrel Caliber: 9mm • Barrel Profile: Flame Fluted, Drop In • Barrel Material: 416-R Stainless Steel • Barrel Twist: 1:10 • Muzzle Thread: 1/2x28 TPI • Crown: 11-degree Target Crown • Rifling Method: Button • Rifling Type: Conventional • Inside Finish: Salt Bath Nitride • Outside Finish: Salt Bath Nitride • Not compatible with M17 or X Series pistols (including the X5 and X5 Legion)
