Sig Sauer P226 9mm Luger Barrel, M13.5x1 LH Threaded, with Thread Protector - Steel Black

The Sig Sauer P226 9mm Luger barrel is a genuine factory replacement built for shooters who want to run suppressors or other threaded muzzle devices on one of the most trusted service pistols in the world. This steel barrel comes with a left-hand thread pitch of M13.5x1 LH—the specification that pairs with Sig's P226 platform—and includes a knurled thread protector cap to keep the threads clean and protected when no device is mounted. Whether you're refreshing a worn barrel, adding a suppressor-ready option to your carry gun, or building a specialized setup for reduced-noise shooting, this is OEM Sig hardware engineered to the same standards as the original.

Sig Sauer factory barrels are specially heat-treated to withstand the pressures and wear that come with regular use. The result is a component built to last—no guesswork, no aftermarket compromise. The left-hand thread orientation is critical for P226 compatibility, so confirm your pistol's specs before ordering. The included thread protector is a thoughtful touch that keeps your barrel threads in shootable condition between suppressor outings.

This barrel is ideal for hunters and precision shooters who want to suppress their 9mm P226 without sacrificing the reliability Sig is known for. It's also a solid choice for anyone rebuilding a pistol or rotating out a barrel that's seen heavy use. Factory OEM barrels give you confidence that everything will function exactly as Sig designed it.
