The Sig Sauer P226 Replacement Barrel (brand part no. BBL22640) is a factory-spec .40 S&W barrel machined from black nitride steel for the P226 platform. Sig Sauer specially heat-treats its factory replacement pistol barrels for toughness and durability, and this one carries the same 4.4-inch length as the barrel the P226 ships with, so lockup and point of impact stay consistent with the pistol’s original geometry. As a genuine Sig Sauer part, it’s a straightforward, factory-correct way for P226 owners to replace a worn barrel or set up a dedicated .40 S&W upper.
