The Sig Sauer P320/P250 Compact Replacement Barrel (brand part no. BBLMODC40) is a factory .40 S&W barrel built to fit either the P320 Compact or P250 Compact frame. Sig Sauer chambers it in .40 auto and finishes it in the brand’s black Nitron coating, matching the corrosion resistance and appearance of the barrel the pistol shipped with. Swapping it in is a tool-free job: unload the firearm, remove the slide from the receiver or grip module, slide out the factory barrel, and drop this one into place. At 3.90 inches, it keeps the pistol’s factory dimensions and slide cycling unchanged, making it a clean option for owners who need a factory-correct replacement or a dedicated .40 S&W barrel for a Compact-frame P320 or P250.
