Sco Threaded Barrel for Sig P320c 9mm 1/2x28$143.65
Availability: In Stock
If you're ready to run a suppressor on your Sig P320 Full-Size, the SilencerCo threaded barrel for Sig P320 Full-Size 9mm delivers the foundation you need. This is a direct factory-spec replacement barrel that threads on to accept 1/2x28 suppressors — opening up a whole category of sound-reduction options for range work, hunting, and defensive training without requiring a complete build or gunsmith visit.
Built from 416R stainless steel and finished in non-reflective black nitride, the SilencerCo threaded barrel maintains the reliability and point-of-aim accuracy of your stock P320. The 1-10" twist rate handles standard 9mm ammunition as your rifle does, so you're not trading inherent performance for the ability to suppress. Every barrel ships with a thread protector, so you can shoot suppressor-ready without worrying about thread damage when running the gun bare.
This is a no-compromise part swap — drop it in and your P320 is suppressor-compatible. Whether you're a serious handgun competitor, a hunter looking to keep hearing protection low on the priority list, or someone who simply prefers a quieter training session, a threaded barrel is the fastest way to make that happen on a full-size P320.
