The Sig Sauer P220 Threaded Barrel (brand part number BBL22045CPTB) is a genuine Sig Sauer replacement barrel for the P220, chambered in .45 ACP and cut with a threaded muzzle for a suppressor or compensator. The barrel is chrome lined and phosphated, a combination Sig uses for extreme corrosion resistance, giving you a durable bore that also opens up your P220 to muzzle device options the standard barrel doesn’t support. Cut with a 1:16-inch twist, it’s a straightforward factory-spec upgrade or replacement.
