KKM barrels are made using certified stainless steel gun-barrel quality bar stock. Our advanced proprietary button rifling process allows KKM barrels to offer greater accuracy over stock conventionally rifled barrels. Our Sig Sauer barrels come with fully supported SAAMI spec match chambers for shooting factory or reloaded ammunition as well as lead or jacketed bullets. Our P320X5 barrels are drop-in fit for the majority of first generation and Legion models. If fitting is required then most of the time the hood length will have to be fit to your slide by a gunsmith.
