• Non-reflective black nitride finish
• 1/2"-28 tpi threads accept a wide variety of popular pistol suppressors
• 1-10" twist rate preserves your 320’s accuracy
• Models available for both full-size and compact P320

Precision machined to factory specs, the Silencerco SIG P320 Threaded Barrel won’t alter the reliability or performance of your P320.
