IBS Ported Barrel for Sig Sauer P365
Zaffiri Precision IBS Barrels are designed specifically for use with IBS slides, offering an integrated ported system built around precise alignment between the barrel and slide. Machined from 416R stainless steel at our facility in Largo, Florida, these barrels are built for consistent fitment and dependable operation with standard components. The chunk port design vents gases through the slide cutouts, helping to reduce muzzle rise and felt recoil while maintaining a clean, purpose-built configuration. A great choice for shooters building out a complete IBS system using compatible Zaffiri Precision components.
Please note that this barrel is designed specifically to work with ONLY WITH OUR ZP IBS Ported Sig Sauer P365 Slide
THIS BARREL HAS A LOADED CHAMBER INDICATOR (LCI) NOTCH. Some states REQUIRE a Loaded Chamber Indicator – please check your firearm and local, state, federal and all other regulatory laws.
