SilencerCo AC5367 9mm Luger 3.7" Threaded Barrel - Fits Sig P365

The SilencerCo AC5367 is a drop-in 9mm Luger threaded replacement barrel purpose-built for the Sig P365 micro-compact pistol. Machined from 416R stainless steel and finished in a durable black nitride coating, this barrel delivers the precision, corrosion resistance, and longevity expected from a premium pistol component.

Featuring a 3.7" barrel with a 1:10 right-hand twist and standard 1/2x28 muzzle threading, the AC5367 lets P365 owners mount a suppressor or 9mm compensator using common muzzle accessories. The threaded muzzle ships with a thread protector installed for safe, snag-free carry when no device is attached. With no sights machined into the barrel, the AC5367 is intended for use with the Sig P365's factory slide and existing sighting system.

Whether you are upgrading your Sig P365 for suppressed shooting or simply replacing a worn factory barrel, the SilencerCo AC5367 offers a purpose-built 9mm Luger solution backed by SilencerCo's reputation for quality suppressor-ready components.
