Description
The Sig Sauer BBLMODF40 is an OEM replacement barrel purpose-built for the Sig Sauer P320 Full-Size and P250 Full-Size pistols. Machined from steel and finished in a durable Black Nitride coating that boosts surface hardness and resists wear, this is a factory-spec barrel that delivers the accuracy and long service life shooters expect from Sig Sauer.
Chambered in .40 S&W with a 4.70 inch length, the BBLMODF40 is a direct drop-in replacement that matches the original factory barrel dimensions. It will also drop into any .357 SIG P320 or P250 Full-Size frame with no additional parts required, giving you a simple path to swap calibers between pistols. The barrel ships without sights, ready to install on any standard P320 slide.
Whether you are replacing a worn original, building out a caliber-conversion slide, or simply keeping a spare on hand for the range, this Sig Sauer factory barrel is built to the original P320 Full-Size specifications.
