Silencerco AC5367 Threaded Barrel for Sig P365 - Precision Fit & Enhanced Performance

The SilencerCo AC5367 is a threaded barrel for the Sig P365 9mm, purpose-built for shooters who want to run a suppressor on one of the most popular concealed-carry pistols on the market. If you're planning to add a can to your EDC setup, a quality threaded barrel is the foundation—and SilencerCo engineered this one to deliver the precision fit and durability you need. The barrel is constructed from stainless steel with black nitride finish, combining corrosion resistance with a clean, durable look that holds up to suppressed shooting and regular use.

SilencerCo's reputation in the suppressor world extends to their complement of hosted accessories, and this barrel reflects that standard. The threading is cut to specification for Sig P365 compatibility, so you're getting a drop-in solution that respects the tight tolerances of the frame and action. Whether you're building out a suppressed carry gun or want a dedicated quiet-shooting setup, this barrel gives you the platform to do it right.

The black nitride finish isn't just cosmetic—it's a proven choice for corrosion protection and reduced friction, especially valuable if you're running suppressed (where heat and powder residue are concentrated). The stainless steel core ensures long-term reliability even with heavy use. For P365 owners serious about suppressor ownership, this is the piece that makes it happen.
