Sig Sauer P229-1 9mm Luger 4.4" Threaded Barrel w/ Thread Protector - Black Steel
The Sig Sauer P229-1 9mm Luger threaded barrel is a quality replacement or upgrade component for shooters looking to add suppressor-ready capability to their E2 grip-style P229 platform. With a 4.4" length and factory thread protector included, this barrel transforms your P229 into a suppressor-host without requiring additional muzzle work. The black steel construction has been heat-treated for durability, making it a solid choice for duty, sport shooting, or serious recreational use.
Sig Sauer's P229 remains one of the most trusted compact duty pistols in the world, and having a dedicated threaded barrel in your setup opens up flexibility for both suppressed and unsuppressed shooting. The included thread protector keeps the muzzle clean and protected when you're running it suppressor-free. If you're building a modular 9mm Luger platform or simply want to future-proof your carry gun for sound management, this is a straightforward drop-in solution.
Fit and function depend on using the correct model for your grip style—this barrel is engineered for E2 configuration P229 frames. The heat-treated steel barrel delivers the hardness and longevity Sig Sauer is known for, and the threaded muzzle is cut to standard 1/2x28 dimensions, compatible with most modern 9mm suppressors on the market today.
