The Sig Sauer Sig BBL P365LS 9mm 4.9" Threaded Barrel 1/2x28 LCI is a factory replacement barrel built specifically for the P365 Fuse. Precision machined and finished in durable nitride, this extended 4.9" barrel adds a threaded muzzle for easy attachment of compatible muzzle devices or suppressors while maintaining reliable function with the loaded chamber indicator slide.

This barrel is ideal for shooters who want to stretch the capabilities of their P365 Fuse at the range or during focused training sessions. The longer length supports improved velocity and sight tracking, while the 1/2x28 threads open the door to sound suppression or recoil‑reducing accessories. It is a straightforward upgrade that preserves the compact handling of the pistol and reflects Sig Sauer’s attention to fit, consistency, and long-term durability.
